Which of the following statements describes a common characteristic of catabolic pathways?
A) They combine small molecules into larger, more energy-rich molecules.
B) They require energy from ATP hydrolysis to break down polymers into monomers.
C) They are endergonic and release energy that can be used for cellular work.
D) They are exergonic and provide energy that can be used to produce ATP from ADP and ᵢ.

Quizplus · Accepted Answer

Catabolic pathways are exergonic, meaning they release energy. This energy can be used to produce ATP from ADP and Pi for cellular work. Option A describes anabolic pathways, where larger molecules are formed from smaller ones. Option B describes the process of hydrolysis, which is involved in breaking down large molecules into smaller units, but not a characteristic of catabolic pathways. Option C is incorrect because catabolic pathways are exergonic, meaning they release energy, not endergonic, which require energy input.
