Aerobic oxygen using respiration occurs in three stages. Yes all cells must carry out cellular respiration to obtain usable energy needed for other functions in the cell. We need to breathe oxygen so that our cells can perform cell respiration and ultimately help us convert glucose into atp.
Depending on the organism and circumstance cellular.
Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. What are the cell processes. This results in a net gain of two atp molecules. In glycolysis glucose is split into two molecules of pyruvate.
