The purpose of coupling two biochemical reactions is to
A)lower the activation energies of both reactions.
B)convert an endergonic reaction to an exergonic one.
C)convert an exergonic reaction to an endergonic one.
D)use an endergonic reaction to drive an exergonic reaction.
E)use an exergonic reaction to drive an endergonic reaction.

Question

Quizplus · Accepted Answer

Coupling two biochemical reactions allows the energy released from an exergonic reaction to drive an endergonic reaction. This allows for the overall reaction to occur spontaneously, as the energy released by the exergonic reaction compensates for the energy required for the endergonic reaction.
