Epinephrine and glucagon have which one of the following effects on glycogen metabolism in the liver? The net synthesis of glycogen is increased. Glycogen phosphorylase is activated, whereas glycogen synthase is inactivated. Both glycogen phosphorylase and glycogen synthase are activated but at significantly different rates. Glycogen phosphorylase is inactivated, whereas glycogen synthase is activated. cAMP-dependent protein kinase is activated, whereas phosphorylase kinase is inactivated.
