Cells use oxygen to break down glucose and release its energy during a process called cellular respiration. The series of metabolic processes by which living cells produce energy through the oxidation of. Cellular respiration is the process by which cells convert nutrients into the energy that is used to power a variety of functions like transportation, locomotion, and the synthesization of macromolecules.

If it requires oxygen it is called aerobic respiration, whereas if it takes place in the absence of oxygen it is anaerobic respiration. Cell respiration a catabolic process (see catabolism) occurring in cells where complex organic molecules are broken down to release energy for other cellular processes. In the absence of oxygen, cells can get energy by breaking down food through the process of fermentation, or anaerobic respiration. Aerobic respiration occurs with oxygen and releases more energy but more slowly.
