making a bond (adding a phosphate)

|
breaking a bond (removing a phosphate)
|
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: -In biochemistry, dephosphorylation is the removal of a phosphate (PO43−) group from an organic compound by hydrolysis.
Detailed explanation-3: -The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).
Detailed explanation-4: -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.
Detailed explanation-5: -The release of one or two phosphate groups from ATP, a process called dephosphorylation, releases energy.
