In order for cellular respiration to take place, mitochondria must have oxygen. Mitochondria are the building blocks of the cell, and the cell cannot survive without it.
Cells cannot perform their functions. Cells need two things to function: fuel and oxygen. These allow all the cells in your body to produce energy to do any work that you want to do, like digesting or thinking. Without oxygen, your cells cannot undergo cellular respiration. It will fall back on anaerobic respiration, which produces less energy and has a by-product of lactate (Iactic acid). Failing that, your cells will begin to shut down.
