Why is ATP important in the metabolism or organisms? a. It hydolyzes to add free energy to exergonic reactions. b. The terminal phosphate bond has higher energy than the other two phosphate bonds. c. The terminal phosphate is held by a strong covalent bond that when hydrolizes, captures free energy. d. ATP provides energy coupling between exorgonic and endergenic reations

ATP provides energy coupling between exergonic and endergonic reactions.

Explanation:

Adenosine triphosphate is an important molecule found in the cells and its role is to transport energy that is necessary for the cell or metabolic activities. These activities include muscle contraction and nerve impulse propagation.  The ATP provides energy to both the energy consumption actions and energy-releasing reactions and thus needs a small amount of input of energy. The chemical bonds on breaking provide energy for cells to work.
