An increase in glucagon will cause

Question

Quizplus · Accepted Answer

Glucagon stimulates liver glycogenolysis, which means breaking down stored glycogen in the liver into glucose and releasing it into the bloodstream. This process increases blood glucose levels. Therefore, an increase in glucagon will cause an increase in liver glycogenolysis. Choice B is incorrect because an increase in glucagon will actually increase blood glucose levels, not decrease it. Choice C is also incorrect because glucagon activates rather than inactivates liver adenyl cyclase. Choice D is incorrect because glucagon does not stimulate muscle glycogenesis, but rather stimulates protein breakdown in muscle tissue to provide amino acids for gluconeogenesis in the liver.
