Answer:
Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. ... When energy is needed by the cell, it is converted from storage molecules into ATP. ATP then serves as a shuttle, delivering energy to places within the cell where energy-consuming activities are taking place.
ATP carries energy. When the phosphate is removed, energy is released and ATP becomes ADP—adenosine diphosphate. ADP is a lower-energy molecule that can be converted into ATP by the addition of a phosphate group. If ATP is a wallet filled with money, ADP is a nearly empty wallet.
