Explain (HT only) how insulin and glucagon interact in a negative feedback cycle to control blood glucose concentration.

In the subtopic Control of blood glucose concentration, this learning objective focuses on explain (HT only) how insulin and glucagon interact in a negative feedback cycle to control blood glucose concentration. 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 blood glucose, glucagon, HT only, insulin, and negative feedback. insulin means a hormone secreted by the pancreas that lowers blood glucose concentration by facilitating the uptake of glucose into cells. Avoid students often confuse the roles of insulin and glucagon in the negative feedback cycle, thinking that both hormones lower blood glucose levels; instead 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. For exam answers, create a flowchart that illustrates how insulin and glucagon interact in the negative feedback loop to regulate blood glucose levels.
