Question

Glycogen __________ enzyme that catalyzes the addition of glucose to glycogen. Glycogen ____________ is the enzyme that removes glucose molecules from oxygen.

a) Synthesis; Phosphorylase
b) Breakdown; Synthase
c) Synthase; Phosphorylase
d) Breakdown; Phosphatase

Answer 1

The correct enzymes related to glycogen metabolism are glycogen synthase for the addition of glucose to glycogen, and glycogen phosphorylase for the removal of glucose from glycogen, making the complete answer c) Synthase; Phosphorylase.

Step-by-step explanation:

The correct answer to the question “Glycogen __________ enzyme that catalyzes the addition of glucose to glycogen.” is synthase, as glycogen synthase is responsible for adding glucose units to the glycogen molecule through the formation of α-1→4 glycosidic linkages. The second part of the question is “Glycogen ____________ is the enzyme that removes glucose molecules from glycogen.” The answer here is phosphorylase, as glycogen phosphorylase is the key enzyme in glycogenolysis, removing glucose units by hydrolyzing the α-1→4 linkages in the glycogen molecule until it reaches a branching point, where other specialized enzymes take over. Therefore, the complete answer is c) Synthase; Phosphorylase.
