Question

Which of the following statements about catabolic pathways is false?

a) They involve the breakdown of complex molecules.
b) They release energy.
c) They are anabolic.
d) They often involve enzyme-catalyzed reactions.

Answer 1

The false statement about catabolic pathways is that they are anabolic; catabolic pathways break down complex molecules into simpler ones and release energy. The correct option is C.

Step-by-step explanation:

Among the provided statements about catabolic pathways, the false one is (c) They are anabolic. Catabolic pathways involve the breakdown of complex molecules into simpler ones, and this process releases energy. This is in contrast to anabolic pathways, which require energy to synthesize larger molecules from smaller ones.

Despite their differences, both catabolic and anabolic pathways are essential for maintaining the cell's energy balance. Additionally, catabolic reactions often involve enzyme-catalyzed reactions which help to speed up the biochemical processes.
