Verified step by step guidance

Understand the role of insulin in glycogen metabolism: Insulin is a hormone that promotes glycogen synthesis by activating glycogen synthase, which is responsible for converting glucose to glycogen.

Examine the role of glucagon: Glucagon is a hormone that typically promotes glycogen breakdown in the liver, not inhibits it. It activates glycogen phosphorylase, which breaks down glycogen into glucose.

Consider the effect of epinephrine: Epinephrine, also known as adrenaline, stimulates glycogen breakdown in muscle cells by activating glycogen phosphorylase, providing energy for muscle activity.

Review the activation of glycogen phosphorylase: Glycogen phosphorylase is activated by phosphorylation, which is a process where a phosphate group is added to the enzyme, enhancing its activity to break down glycogen.

Identify the incorrect statement: Based on the understanding of hormone functions, the statement 'Glucagon inhibits glycogen breakdown in the liver' is incorrect because glucagon actually promotes glycogen breakdown.
