Question

Quizplus · Accepted Answer

Catabolism is the breakdown of complex molecules into simpler ones, releasing energy. This process is exergonic (energy is released). On the other hand, anabolism is the synthesis of complex molecules from simpler ones, requiring energy. This process is endergonic (energy is absorbed). Therefore, the correct pair of terms that complete the sentence are exergonic and endergonic.
