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.
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration. Respiration is also the process by which once-living (organic) organisms are decomposed.
