  1. The answer is hyperglycemia. Since glucagon catalysis glycogenolysis reaction which is the formation of glucose from glycogen in the liver and muscle cells. Hyperglucagonemia which is high level of glucagon in the blood will increase the rate at which glucose is being formed from glycogen and hence leading to high levels of glucose in the blood (hyperglycemia).
