Because muscles lack receptors for glucagon,what hormone activates muscle glycogen phosphorylase?

Question

Quizplus · Accepted Answer

Adrenaline is the hormone that activates muscle glycogen phosphorylase. Glucagon primarily stimulates liver glycogenolysis and gluconeogenesis, but has little effect on muscle glycogen. Insulin enhances glucose uptake and storage in muscle and adipose tissue, but does not activate glycogen phosphorylase. Glycogenin is an enzyme involved in glycogen synthesis. UDP-glucose is a co-substrate for glycogen synthesis and does not activate glycogen phosphorylase.
