Which of the following is best associated with a coupled reaction?
A) ATP consumes energy from another metabolic reaction.
B) ADP often transfers a phosphate to the reactant.
C) The breakdown of ATP generally releases more energy (and heat) than is needed to power the metabolic reaction.
D) ATP gains a phosphate group during the metabolic reaction.
E) ADP is used up in the metabolic reaction.

Question

Quizplus · Accepted Answer

Coupled reactions involve using the energy released from one process (like the breakdown of ATP) to drive another process. The breakdown of ATP into ADP and a phosphate group releases energy, part of which is then used to power another metabolic reaction, often requiring less energy than what is released, making choice C the best association with a coupled reaction.
