Which of the following statements best describes the 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 from ATP stores free energy that is used for cellular work.
D) The terminal phosphate bond is stronger than most covalent bonds in other biological macromolecules.

Question

Quizplus · Accepted Answer

ATP acts as an intermediary molecule that couples exergonic (energy-releasing) reactions to endergonic (energy-requiring) reactions within the cell, thereby allowing the cell to conduct necessary activities such as mechanical work, transport, and synthesis of biomolecules.
