Chemical energy that is stored in food molecules is released through cellular respiration. Part of this energy is kept as adenosine triphosphate, or ATP.

Anaerobic metabolism of glucose is a step-wise biochemical process called glycolysis or fermentation and can be performed by most cells in humans, animals and plants. Glycolysis occurs in the cytosol -- the liquid portion of the cell -- and produces energy quickly but not that efficiently.
