Common mistake
Misunderstanding Glucagon's Role
Students often confuse glucagon with insulin, thinking both hormones have the same function in blood glucose regulation.
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.
