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.
A cell's energy supply is highly dependent on cellular respiration. It may be performed as aerobic or anaerobic respiration. Aerobic respiration requires the intake and combination of oxygen with water molecules to convert glucose into energy to be used by cells. Anaerobic respiration allows for the conversion of glucose into energy without the presence of oxygen. It is utilized by bacteria or when an organism has a low supply of oxygen.
