Question

Which structure ATP or ADP contains more stored energy? Where is the energy stored

Answer 1

The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.
