A catabolic pathway may be which of the following?
A) a set of reactions that combine monomers into larger, more energy-rich polymers
B) a set of coupled reactions that are endergonic
C) a set of reactions that form covalent bonds between molecules to store free energy
D) a set of reactions that release energy that can be used to drive cellular work

Question

Quizplus · Accepted Answer

A catabolic pathway is a set of reactions that break down complex molecules into simpler ones, releasing energy that can be used by the cell to perform work. Therefore, option D is the correct answer. The other options are not describing catabolic pathways. A) is anabolic, as it is combining monomers into larger polymers. B) is not describing a catabolic pathway, as it is endergonic and requires energy. C) is not describing catabolic pathways, as it is referring to the formation of covalent bonds to store energy, not the release of energy.
