Explain (HT only) that glucagon causes glycogen to be converted back into glucose.

In the subtopic Control of blood glucose concentration, this learning objective focuses on explain (HT only) that glucagon causes glycogen to be converted back into glucose. Within Hormonal coordination in humans, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include glucagon, glycogen, and HT only. glucagon means a hormone secreted by the pancreas that stimulates the conversion of glycogen back into glucose when blood glucose levels are low. Avoid students often confuse glucagon with insulin, thinking both hormones have the same function in blood glucose regulation; instead remember that glucagon's role is to increase blood glucose levels by converting glycogen back into glucose, while insulin lowers blood glucose levels by facilitating glucose uptake into cells. For exam answers, focus on how glucagon functions in the body, particularly its role in converting glycogen back into glucose when blood sugar levels are low.
