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.

The answer is energy is transferred from an exergonic process to an endergonic one. That is what energy coupling is. The exergonic process will release free energy and this free energy will be absorbed by the endergonic process. It can also drive the endergonic process.
