<P> ATP hydrolysis is the reaction by which chemical energy that has been stored in the high - energy phosphoanhydride bonds in adenosine triphosphate ( ATP ) is released , for example in muscles , by producing work in the form of mechanical energy . The product is adenosine diphosphate ( ADP ) and an inorganic phosphate , orthophosphate ( P ) . ADP can be further hydrolyzed to give energy , adenosine monophosphate ( AMP ) , and another orthophosphate ( P ) . ATP hydrolysis is the final link between the energy derived from food or sunlight and useful work such as muscle contraction , the establishment of electrochemical gradients across membranes , and biosynthetic processes necessary to maintain life . </P>
what is the breakdown product formed when one phosphate group is removed from atp
adenosine diphosphate ( ADP ) an inorganic phosphate , orthophosphate ( P )
