Which of the following holds true for energy coupling?

Energy is released in an exergonic reaction.

Energy is transferred from an exergonic process to an endergonic one.

Energy is consumed in an endergonic reaction.

I think the correct answer from the choices listed above is option A. Energy coupling is characterized by a release of energy in an exergonic reaction. These reactions usually do not require energy to happen, and therefore occur spontaneously. Hope this answers the question.
