Question

Quizplus · Accepted Answer

Catabolic pathways break down larger molecules into smaller ones, releasing energy that can be used by the cell to drive cellular work. Option A is incorrect because catabolic pathways break down molecules, not combine them. Option C is incorrect because catabolic pathways release energy, making them exergonic. Option D is incorrect because catabolic pathways break down molecules into simpler ones, not build up complex molecules.
