Which of the following statements describes a central role that ATP plays in cellular metabolism?
A) Hydrolysis of ATP provides an input of free energy for exergonic reactions.
B) ATP provides energy coupling between exergonic and endergonic reactions.
C) Hydrolysis of the terminal phosphate group stores free energy that is used for cellular work.
D) Its terminal phosphate bond is stronger than most covalent bonds in other biological macromolecules.

Question

Quizplus · Accepted Answer

ATP provides energy coupling between exergonic and endergonic reactions, allowing energy to be transferred from one reaction to another within the cell. This is because ATP has high-energy phosphate bonds that can be broken to release energy, which is then used to drive endergonic reactions.
