Question

Quizplus · Accepted Answer

Glucagon signals the liver to break down glycogen into glucose, which can be released into the bloodstream. Glycogen phosphorylase is the enzyme responsible for catalyzing the first step in glycogen breakdown, and its activity is increased in response to glucagon. Therefore, glycogen phosphorylase is activated in liver tissue in response to a glucagon signal.
