Question

Quizplus · Accepted Answer

The breakdown of macromolecules releases energy and is an exergonic process, while the biosynthesis of macromolecules requires energy and is an endergonic process. This mirrors the relationship between exergonic (energy-releasing) and endergonic (energy-requiring) reactions in metabolism.
