Protein kinase A regulates glycogen metabolism by _______ glycogen synthase and _______ glycogen phosphorylase.

Question

Quizplus · Accepted Answer

Protein kinase A phosphorylates and inhibits glycogen synthase, thereby inhibiting glycogen synthesis. It also phosphorylates and activates glycogen phosphorylase, promoting glycogen breakdown. Therefore, protein kinase A regulates glycogen metabolism by inactivating glycogen synthase and activating glycogen phosphorylase.

Protein Kinase a Regulates Glycogen Metabolism by _______ Glycogen Synthase
