Several products are released during the hydrolysis of ATP.
The products released are adenosine diphosphate or ADP, an inorganic phosphate
and orthophosphate. These are the
products initially released during the hydrolysis of ATP. The other things that
are released during this reaction or further hydrolysis of ATP are adenosine
monophosphate, energy, another orthophosphate and water. Actually energy is needed to hold the third
phosphate with ADP. So when hydrolysis is done and the third phosphate is
released, energy also gets released.
