What conversion represents a catabolic reaction?
A) Glucose to glycogen
B) Amino acids to protein
C) Fatty acids and glycerol to triglycerides
D) Glycogen to glucose
E) Glucose to protein

Question

Quizplus · Accepted Answer

Catabolic reactions involve the breakdown of complex molecules into smaller ones, releasing energy in the process. The conversion of glycogen to glucose is a catabolic process because it breaks down a complex molecule (glycogen) into smaller ones (glucose molecules) and releases energy in the process. The other choices listed are all anabolic reactions because they involve the building up of complex molecules from simpler ones, which requires an input of energy rather than releasing it.
