In ATP, which bond is broken when energy is released and when energy is added which bond forms?

Energy is released from ATP by the breaking of the phosphate bond. A denosine triphosphate, or ATP, consists of a sugar called ribose, the molecule adenine and three phosphate groups. During the hydrolysis of ATP, the last phosphate group is transferred to another molecule, thus breaking the phosphate bond. This reaction causes energy to be released to power other activities within the cell.
