Answers

1. Iodoacetamide combines with the thiol group of cysteine, thus, the protein cannot produce a disulfide bond. So, iodoacetate is an inhibitor of cysteine peptidase.  

2. In the presence of competitive inhibition, the Km increases. In the presence of a competitive inhibitor -1/Km increases, thus, 1/Km decreases, and hence Km increases. The competitive inhibitors work by combining reversibly with the active site of an enzyme. Thus, more concentration of substrate is required to attain half of the maximum velocity.  

3. In the given case, half of the molecules of the enzyme are completely active and half of the molecules of the enzyme are completely inactive.  

Irreversible inhibition is one of the reasons for the reduction in the rate of an enzyme-catalyzed reaction in the given case. The loss of activity of the enzyme molecules due to irreversible inhibition is time dependent and it is the reason behind the reduction in reaction rate.  

Reduction in the rate of reaction is proportional to the loss of activity. Therefore, a 50 percent reduction in reaction rate will result in 50 percent of the enzyme molecules to be inactive and the other 50 percent of the enzyme molecules to be completely active.  

4. The statement, that is, in the majority of the cases, the inhibitor can be removed by dialysis is not true about irreversible enzyme inhibitors.  

The irreversible inhibitors combine with the enzymes permanently and make covalent bonds with the enzyme. Therefore, it cannot get removed by the process of dialysis in the majority of cases.  

5. The correct statement is that the initial velocity increases in the presence of an enzyme.  

6. The correct statement is that the Vmax is attained when the concentration of the substrate is double the Km.  

The Km is illustrated as the concentration of substrate at which the reaction velocity reaches half of the maximum velocity. Therefore,  

Km = 1/2 Vmax

2 Km = Vmax

Vmax = 2 Km


Final answer:

An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. In the presence of competitive inhibitors, Vmax decreases and Km increases. When an irreversible site-specific inhibitor is added to an enzyme operating at very high substrate levels, the reaction rate is reduced by 50%, resulting in half of the enzyme molecules being completely active and half of the enzyme molecules being completely inactivated.

Explanation:1. Irreversible Inhibition

An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. When the inhibitor is bound, the enzyme active site is blocked, the substrate does not bind, and catalysis cannot occur, similar to competitive inhibition. The difference here is that the inhibition is irreversible, meaning that the inhibitor remains bound and does not dissociate from the enzyme because the enzyme-inhibitor covalent bonds are not easily broken.

2. Competitive Inhibition

Competitive inhibition is when an inhibitor reversibly binds to an enzyme at the enzyme active site; competing with the substrate for binding. A competitive inhibitor must be a molecule that is structurally similar to the substrate molecule, allowing it to interact with the enzyme active site through similar non-covalent interactions, but it does not, or cannot, undergo the same chemical reaction. When the inhibitor is bound to the active site, it blocks the correct substrate from binding and catalysis from occurring. However, as a reversible inhibitor, it can disassociate from the enzyme eventually allowing for the correct substrate to bind and the catalysis to occur.

3. Enzyme Kinetics

In the presence of an irreversible site-specific inhibitor, the reaction rate is reduced by 50%. This indicates that half of the enzyme molecules are completely active and half of the enzyme molecules are completely inactivated. The substrate, on the other hand, can still bind to all available active enzyme molecules, but the binding affinity may differ for each enzyme molecule.

Which process stops when a ribosome reaches a stop codon? transcription splicing replication translation

Answers

I beleive its Translation

Answer:

The correct answer will be translation.

Explanation:

Ribosomes are cell organelles present either in cytoplasm or attached to endoplasmic reticulum in protoplasm of a cell.

They are involved in the process of translation or the synthesis of protein by translating the coded information of mRNA into amino acids to form proteins. So, they are also known as translators of cell.

Protein synthesis starts during the initiation phase of translation after reading start codon (AUG). Translation terminates when ribosome reaches   any of the stop codons that is UGA, UAA, and UAG at 3'-end the synthesized polypeptide will dissociate from the ribosome.

Thus, translation will be the correct answer.

Large molecules, such as glucose, that cannot cross the lipid bilayer can still move across the membrane through a type of passive transport called?

Answers

Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.

Which of the following is a negative effect of algal blooms on the environment

Answers

Algae die quickly, so aerobic decomposers come in to decompose dead algae. In this process, decomposed use all the oxygen in an area, thus making that area oxygen deficient, meaning no organisms can live there

Final answer:

Algal blooms can result in dead zones due to oxygen consumption by bacteria, and the production of toxins by certain algae can cause health risks and economic losses. Responsible use of fertilizers and wetland restoration are essential measures to prevent harmful effects on the environment.

Explanation:

Negative Effects of Algal Blooms on the Environment

One negative effect of algal blooms on the environment is the creation of dead zones in aquatic ecosystems. As an algal bloom occurs and the algae subsequently die, they provide a significant amount of organic matter to deep-water bacteria, resulting in a surge of bacterial population growth. These bacteria consume large amounts of oxygen, leading to regions where animal life can scarcely survive due to oxygen depletion. This process is detrimental to aquatic life and disrupts the natural balance of the ecosystem.

Another harmful impact of algal blooms is the production of toxins by certain species of algae such as Karenia brevis, which causes red tides, and cyanobacteria. These toxins can be fatal to fish and accumulate in shellfish, posing health risks to humans who consume them and causing economic losses due to the closure of affected fisheries. In addition, the presence of cyanobacterial toxins like microcystins can lead to allergic reactions and liver damage when ingested in contaminated water.

In conclusion, although fertilizers provide benefits for crops and are not easily banned for political and economic reasons, the resultant algal blooms necessitate responsible fertilizer use, regulation, and efforts like wetland restoration to mitigate the excess nutrients entering aquatic systems.

The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. Label each arrow with the type of energy being transferred.

Answers

Final answer:

The arrows in the diagram represent the transfer of energy in an ecosystem. Energy enters the ecosystem through photosynthesis and flows from plants to herbivores to carnivores. The arrows can be labeled with the type of energy being transferred.

Explanation:

The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. To label each arrow with the type of energy being transferred, we need to understand the flow of energy in an ecosystem. Energy enters the ecosystem through photosynthesis, which converts sunlight into chemical energy in plants. This energy is then passed from producers (plants) to herbivores (animals that eat plants) and then to carnivores (animals that eat other animals).

For example, the arrow from the sun to the plant represents the transfer of solar energy through photosynthesis. The arrow from the plant to the herbivore represents the transfer of chemical energy from the plant to the herbivore. And the arrow from the herbivore to the carnivore represents the transfer of chemical energy from the herbivore to the carnivore.

Crossing over is the process during which a homologus chromosome change their sequence . Crossing over occur to increase the genetic diversity. It is very important because due to this gentic varatation increase. In a first divisions of meiosis crossing over occur and sister chromatids are formed when chormosme are replicated into two stands .

Final answer:

Crossing-over is an event during prophase I of meiosis where homologous chromosomes exchange genetic material, leading to genetic variety in gametes. This exchange, or recombination, increases genetic diversity, which is vital for evolution and individual uniqueness.

Explanation:

During prophase I of meiosis, a crucial process called crossing-over takes place. Homologous chromosomes pair up gene-for-gene, forming a structure known as a tetrad, which consists of four chromatids. During this pairing, the non-sister chromatids come into proximity and exchange segments of genetic material. This breakage and rejoining of DNA segments results in the chromatids acquiring unique combinations of alleles, thereby increasing genetic diversity in the resultant gametes. This genetic shuffle, also called recombination, happens multiple times and can affect any part of the chromosome, leading to numerous genetic variations.

What is urine formation?

Urine is waste. Mostly water and urea. The body removes urea, a nitrogenous waste product. Filtration, reabsorption, and secretion form urine in the kidney.

Filtration. Kidneys filter blood. Arteries feed the kidney's glomerulus. Bowman's Capsule contains the kidney's glomerulus. Filtration. High-pressure blood forces substances through small capillaries. Walls strain. Filtration.

Filtrate—water, sugar, salts, amino acids, nitrogenous wastes, and other microscopic things—enters the kidney. Cells and large blood proteins stay in arteries. Pre-urinary kidney filtrate.

Reabsorption: Filtrate enters proximal tubule. This kidney filters many chemicals. These are absorbed.

Glucose, salts, vitamins, hormones, and amino acids are restored. The filtrate may retain excess sugar or salt from the body. Because glucose cannot be reabsorbed, high-blood-glucose diabetics may pee glucose. Pre-urine is reabsorbed.

Secretion. The Loop of Henle exchanges water and salt. The distal tubule releases it following the Loop of Henle.

Excretion must be accelerated sometimes. Toxins always leave rapidly. No filtering or absorption. The blood artery secretes them into the distal tubule's almost-formed urine.

Species with a limited variety of phenotypes living in a diverse habitat  will undergo adaptations in order to cope up with environmental variability.  

Rough-skinned newts and common garter snakes are in an "evolutionary arms race." In this phenomenon, two species continually evolve adaptations against one another to increase their own chance of survival. Rough-skinned newts produce tetrodotoxin, a type of poison, as a defense mechanism. Most common garter snakes have some resistance to the toxin. In areas where common garter snakes and rough-skinned newts coexist, rough-skinned newts express very high levels of tetrodotoxin, and common garter snakes have evolved a very high degree of resistance to tetrodotoxin. Based on this information, what is the most likely relationship between common garter snakes and rough-skinned newts?

A.

B. Predator and prey

Answer:

The correct answer would be B. predator and prey.

Predator and prey is a type of natural relationship in which one organism kills and consume the other organism.

For example, a lion is a predator which kills and consume deer (prey).  

During the course of evolution, prey evolves various adaptations to overcome predation and increases its survival rate.

In addition, a predator also evolves to increase its success rate in predation.

Similarly, rough-skinned newts (prey) evolve to produce poison as a defense mechanism and greater snakes (predator) evolve resistance against that poison to increase its survival rates.

When the cerebrum is affected by a head injury, the individual may experience a loss of voluntary movement and impaired speech. The cerebrum is responsible for conscious functions such as problem-solving, speech, and intentional body movements; therefore, damage to this area can lead to difficulties in these areas. Injury to other parts of the brain, like the brain stem, can affect involuntary functions such as breathing regulation and heart rate.

Moreover, depending on where the stroke has occurred or the extent of the injury, one may also experience difficulties in language abilities, sensory perception, and memory, as well as potential personality changes.

Serious brain injuries such as strokes, which can be hemorrhagic or ischemic, often result in immediate and sometimes lasting symptoms that can include paralysis, confusion, and difficulty with speech and memory. Rehabilitation through various therapies can significantly improve functioning, although in many cases some level of disability may remain. It's crucial to accurately assess neurological functions following a brain injury to determine the best course of treatment.

When two adjacent bases in the same strand of DNA dimerize (form a covalent bond between them), what happens to the DNA?

Answers

The DNA of every higher organism consists of two strands which are joined together through bonding between nitrogenous bases. We know well that the base of one strand forms hydrogen bond between the base of the other strand to hold the DNA intact. Thymine always pairs with Adenine and Guanine always pairs with Cytosine, this way an intact and normal DNA structure is formed.

However, sometimes the Ultra violet (UV) rays cause serious damage to DNA. When UV rays are absorbed by DNA, where the bases are thymine or cytosine they add energy at that point. This energy causes the formation of covalent bond between adjacent cytosine- cytosine or thymine-thymine bases of same DNA strand (Please see attached figure). This abnormal process is called the formation of Pyrimidine dimers.  

What harm they can incur to us?

Our body cells have excellent DNA proofreading mechanisms that correct the errors in DNA. But sometimes when DNA has to replicate, the dimers don’t let the DNA polymerase enzyme to correctly read DNA strand because there are abnormal structures. The enzyme incorporates wrong base, at the position of dimers for example if C-C dimer is present, adenine instead of guanine will be added at that position. This causes the presence of incorrect base in newly synthesized DNA.  

This process leads to mutation in the cells which is very common cause of increased risk of cancers nowadays.


Final answer:

Adjacent bases in the same strand of DNA dimerizing (forming a covalent bond) results in distortions in the normal double helix structure of DNA and can disrupt the processes of replication and transcription. This situation can lead to the induction of mutations. A common example is when ultraviolet light induces the bonding of two adjacent thymines.

Explanation:

When two adjacent bases in the same strand of DNA dimerize, a situation like thymine dimer can occur, a covalent linkage forms between two adjacent thymine bases on exposure to ultraviolet radiation. This type of dimer formation results in abnormal covalent bonds within the DNA strand and can produce distortions or kinks in the normal double helix structure of DNA, which in turn can interfere with normal DNA processes including replication and transcription.

While normal DNA structure largely depends on relatively weak hydrogen bonds that connect diverse base pairs (adenine with thymine, and cytocine with guanine), dimerization of two adjacent bases creates a strong covalent bond changing the DNA strand's behavior, interfering with its usual operation and causing possible mutations. An example of this strong dimerization is when ultraviolet light induces dimer formation between two adjacent pyrimidine bases, commonly two thymines, within a nucleotide strand leading potentially to frameshift or point mutations.

What property of water refers to water's ability to move up the stem of a plant against the force of gravity? Surface tension Cohesion Adhesion Capillary action

Answers

Answer:

actually my friend, its capillary action

Explanation:

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.

Capillary action of water refers to water's ability to move up the stem of a plant against the force of gravity.
