Detailed explanation-1: -When the terminal phosphate, from the three phosphate groups in ATP (adenosine triphosphate), is removed, it becomes ADP (adenosine diphosphate) and the energy released is utilised in carrying out any biological function.
Detailed explanation-2: -ATP is Recyclable ADP, the “uncharged” version of the molecule, stands for adenosine diphosphate. The word diphosphate indicates that the molecule has 2 phosphate (PO3) groups. To “charge” ADP, the cell adds a third phosphate group, converting ADP to ATP.
Detailed explanation-3: -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).
