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: -1. ATP consists of adenosine and two inorganic phosphates. 2. When ADP is broken down into ATP, energy is released.

Detailed explanation-3: -ATP breakdown into ADP and Pi is called hydrolysis because it consumes a water molecule (hydro-, meaning “water”, and lysis, meaning “separation”). Figure 7.6. 1: Adenosine Triphosphate (ATP): ATP is the primary energy currency of the cell.

Detailed explanation-4: -Adenosine diphosphate (ADP) is a biological molecule consisting of one adenine, one sugar, and two phosphates. Its most important role is that it is combined with a phosphate molecule to make ATP, the premier energy molecule in living cells. ADP is also used to help activate platelets in clotting.

Detailed explanation-5: -When ATP, the cell’s energy currency, is hydrolyzed to generate ADP and inorganic phosphate, energy is released.
