Which of the following statements is True concerning catabolic pathways?
A)They combine molecules into more energy-rich molecules.
B)They are usually coupled with anabolic pathways to which they supply energy in the form of ATP.
C)They are endergonic.
D)They are spontaneous and do not need enzyme catalysis.
E)They build up complex molecules such as protein from simpler compounds.

Question

Quizplus · Accepted Answer

Catabolic pathways break down complex molecules into simpler ones, releasing energy in the process. This energy is then used to fuel anabolic pathways, which build complex molecules from simpler ones. Therefore, catabolic pathways are typically coupled with anabolic pathways, supplying them with energy in the form of ATP.
