Detailed explanation-1: -When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

Detailed explanation-2: -The release of one or two phosphate groups from ATP, a process called dephosphorylation, releases energy.

Detailed explanation-3: -ATP to ADP – Energy Release This is done by a simple process, in which one of the 2phosphate molecules is broken off, therefore reducing the ATP from 3 phosphates to 2, forming ADP (Adenosine Diphosphate after removing one of the phosphates Pi). This is commonly written as ADP + Pi.

Detailed explanation-4: -The hydrolysis of ATP breaks the bond between the two outer phosphate groups. This releases the outermost phosphate group along with the free energy that was stored in this bond to produce a molecule of adenosine diphosphate, often shortened to ADP.
