Which of these carries the most energy?

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) carries the most energy among the given options as it has three phosphate groups, which is the source of the energy stored in the molecule. When ATP is hydrolyzed, the terminal bond between the second and third phosphate groups is broken, releasing a large amount of energy. ADP (adenosine diphosphate), on the other hand, has only two phosphate groups, and NADH and NAD⁺ are not energy carriers but rather coenzymes involved in cellular metabolism.
