Explanation:
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 ).
Detailed explanation-2: -When phosphate bonds are broken in ATP molecules, the energy produced as a result is harnessed by molecules such as enzymes and is used to power biochemical reactions that result in cellular work. ATP can be “re-energized” by adding an inorganic phosphate to a molecule of ADP which in turn will create ATP.
Detailed explanation-3: -Hydrolysis of ATP Removing or adding one phosphate group interconverts ATP to ADP or ADP to AMP. Breaking one phosphoanhydride bond releases 7.3 kcal/mol of energy.
