Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.
