Lysosomes are organelles found in animal cells that contain digestive and hydrolytic enzymes which break down various substances, including damaged organelles and pathogens. They play a critical role in processes like phagocytosis and autophagy which are essential for the cell's health and efficiency.
Explanation:The lysosome is a type of organelle found in animal cells and it plays a key role in digesting and breaking down various substances within the cell. The types of molecules that would be found inside a lysosome primarily include digestive enzymes and hydrolytic enzymes. These enzymes are crucial in breaking down proteins polysaccharides lipids nucleic acids and even damaged or old organelles.
Furthermore, lysosomes are often involved in the process of phagocytosis where they help the body's immune system destroy pathogens. For instance macrophages a type of white blood cell can engulf a pathogen and then fuse with a lysosome. The pathogen is then destroyed by the lysosome's hydrolytic enzymes.
Lastly another key function of lysosomes is the role they play in the process known as autophagy. This process also referred to as 'self-eating' involves the cell digesting its own structures particularly when they are damaged or unneeded. This function of lysosomes highlights their role in maintaining the cell's health and efficiency.

Hope this helped!
Answer:
The solutions of the given equation are [tex]k=\frac{1}{3}+\frac{2}{\sqrt{3}}[/tex] and [tex]k=\frac{1}{3}-\frac{2}{\sqrt{3}}[/tex].
Explanation:
The given equation is
[tex]9k^2-6k=11[/tex]
Divide both sides by 9.
[tex]k^2-\frac{2}{3}k=\frac{11}{9}[/tex]
If an expression is [tex]x^2+bx[/tex] then we need to add [tex](\frac{b}{2})^2[/tex] in the expression to make it perfect square.
In the above equation [tex]b=\frac{2}{3}[/tex], so add [tex](\frac{1}{3})^2[/tex] on both the sides.
[tex]k^2-\frac{2}{3}k+(\frac{1}{3})^2=\frac{11}{9}+(\frac{1}{3})^2[/tex]
[tex](k-\frac{1}{3})^2=\frac{11}{9}+\frac{1}{9}[/tex]
[tex](k-\frac{1}{3})^2=\frac{12}{9}[/tex]
[tex](k-\frac{1}{3})^2=\frac{4}{3}[/tex]
Taking square root both the sides.
[tex]k-\frac{1}{3}=\pm \sqrt{\frac{4}{3}}[/tex]
Add 1/3 on both the sides.
[tex]k=\frac{1}{3}\pm \frac{2}{\sqrt{3}}[/tex]
Therefore the solutions of the given equation are [tex]k=\frac{1}{3}+\frac{2}{\sqrt{3}}[/tex] and [tex]k=\frac{1}{3}-\frac{2}{\sqrt{3}}[/tex].

A class of chemical called a neurotransmitter is important in the transmission of nerve impulses. Neurotransmitters are packaged by the cell into small, membrane-bound sacs called vesicles. Upon receiving a chemical signal, the vesicles move toward the plasma membrane and fuse with it, releasing the enclosed neurotransmitters from the terminal end of the nerve cell. Which organelle is most likely responsible for packing neurotransmitters into a vesicle?
Anton Von Leeuwenhoek
The Golgi apparatus is the organelle responsible for packing neurotransmitters into synaptic vesicles in a neuron. Small molecule neurotransmitters are packed at the presynaptic terminal, whereas neuropeptides are packed in the cell body and transported to the terminal. This packing and release mechanism is essential for nerve impulse transmission.
Neurotransmitters are crucial for the transmission of nerve impulses between neurons. These chemical messengers are synthesized within neurons and then packed into specialized structures known as synaptic vesicles. The process of packaging neurotransmitters into vesicles is typically carried out by the Golgi apparatus, which is an organelle responsible for modifying, sorting, and packaging proteins and lipids into vesicles.
Small molecule neurotransmitters are synthesized and packaged into vesicles directly within the presynaptic terminal. Meanwhile, neuropeptide transmitters are first synthesized and packaged into vesicles in the neuron's cell body and then transported to the presynaptic terminal through a mechanism called fast axonal transport. The rate of synthesis for small molecule neurotransmitters is often controlled by a rate-limiting step, while neuropeptides depend on axonal transport to reach the presynaptic terminal.
When an action potential arrives at the axon terminal, the influx of calcium ions triggers the fusion of synaptic vesicles with the plasma membrane. Consequently, neurotransmitters are released into the synaptic cleft, allowing them to bind to receptors on the postsynaptic cell and carry on the nerve impulse. The entire process is critical for communication within the nervous system and is the basis of synaptic transmission.
