Chemical energy that is stored in food molecules is released through cellular respiration. Part of this energy is kept as adenosine triphosphate, or ATP. Although fats, proteins and carbohydrates can also be used as fuel for cellular respiration, glucose is most commonly used as an example. Keep Learning.
During this process, glucose from food is broken down into carbon dioxide and water, and energy is released. The process of releasing energy from food is called respiration, or cellular respiration as it is a series of steps that take place within living cells. It is important to not confuse respiration, or oxidizing glucose, with breathing.
