Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells.
During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
or

When ATP is broken down into ADP (Adenosine Diphosphate) and inorganic phosphate then energy is released. During cellular respiration, energy from the chemical bonds of the food you eat must be transferred to ATP.
