Answer
ATP consists of an adenosine molecule bonded to three phosphate groups. During cellular respiration, chemical energy in food is converted into chemical energy stored in molecules of ATP. This occurs when a molecule of ADP uses the energy provided during cellular respiration to bond with a third phosphate group, forming ATP. As a result, the energy from cellular respiration resides in the bond between the 2nd and 3rd phosphate groups in ATP.
