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 involve the breakdown of large molecules into smaller ones, which releases energy that can be used to produce ATP from ADP and Pi. Therefore, catabolic pathways are exergonic reactions. Option A is incorrect because catabolic pathways break large molecules down into smaller ones, not combine small molecules into larger ones. Option B is incorrect because catabolic pathways usually break down polymers into monomers, and this requires energy input, not ATP hydrolysis. Option C is incorrect because catabolic pathways are not endergonic; they are exergonic.
