The matter is present everywhere and composes everything. The cells need matter as it is required to form new atoms and molecules for survival and reproduction.
What is a cell?A cell is the simplest and smallest unit of the organization of an organism that is composed of matter. The matter is involved in all living and nonliving substances and is the most important for biological cells.
Cells are made of atoms and molecules that are matter too and are the basic units that serve as the fundamental unit of life. It is involved in reproduction and is crucial for survival.
The cells are composed of various organelles that perform various activities and functions for the cell to survive and regulate other activities.

Which product does the Krebs cycle require from the electron transport chain?
Answer:
NAD+ and FAD+
Explanation:
Kreb's cycle is process that breaks down acetyl CoA into carbon dioxide and water. It uses NAD+ and FAD+ as electron acceptors for its redox reactions. The NADH and FADH2 formed during Kreb's cycle enter electron transport chain to donate their electrons to oxygen and to get oxidized into NAD+ and FAD+ respectively. Without supply of NAD+ and FAD+ from electron transport chain, the redox reactions of Kreb's cycle cannot occur.
