Answer:
Energy is released during respiration.
Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. Oxygen and glucose are both reactants of cellular respiration.
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
Hope that help.
