Negative feedback
Explanation
The interaction between insulin and glucagon is a negative feedback mechanism that helps maintain blood glucose levels within a narrow range.
Common mistake
Misunderstanding Negative Feedback
Students often confuse the roles of insulin and glucagon in the negative feedback cycle, thinking that both hormones lower blood glucose levels.
Clarify that insulin lowers blood glucose levels by facilitating glucose uptake and storage, while glucagon raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.
