How does ATP release energy that's stored within the molecule?

ATP releases energy stored within the molecule by the procedure known as ATP hydrolysis. In the hydrolysis of ATP, the energy gathered in the high-energy phosphoanhydride bonds in ATP gets discharged due to the dissociation of these bonds, like in muscles, where work is generated in the form of mechanical energy.

The products formed in the process are inorganic phosphate and ADP. This ADP can get further dissociated to produce AMP and another orthophosphate.
