QUESTION 1 Both epinephrine and glucagon have which effect on hepatic glycogen metabolism? Oboth cause increased glycogenolysis and decreased glycogenesis Oboth phosphorylate and activate glycogen phosphorylase and glycogen synthase Oboth phosphorylate and inactivate glycogen phosphorylase and glycogen synthase Oboth cause the synthesis of glycogen to have a net increase

Step 1
When blood glucose is low, glucagon is released, stimulating glycogenolysis (breakdown of glycogen to glucose) in the liver. Epinephrine is released in response to stress, also stimulating glycogenolysis to provide a quick energy source. Show more…

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.

Epinephrine acting on liver cells causes enzymes involved in glycogen metabolism to become __ and, therefore __. (Caution: Think Carefully!!!!) Phosphorylated; either active or inactive, depending on the enzyme Phosphorylated; Active Dephosphorylated; Inactive Dephosphorylated; either active or inactive, depending on the enzyme QUESTION 10 Insulin signaling results in activation of ___ in liver cells resulting in ___. protein kinase a, glycogen synthesis Protein Phosphatase-1; glycogen synthesis Protein phosphatase-1; glycogen breakdown protein kinase a, glycogen breakdown
