The Story: The Thermostat for Sugar

Your blood glucose level is like a heating system. If it gets too high (after eating), the "thermostat" (pancreas) turns down the heat — it releases insulin to lower glucose. If it drops too low (not eaten for a while), the thermostat turns up — releasing glucagon to raise glucose. This is classic negative feedback.

Quick Recall Flashcards

What is glucose regulation?

The process by which cells maintain a stable glucose concentration, essential for energy production and survival.

What triggers glucose regulation?

Low blood glucose levels trigger the release of glucagon, while high levels trigger insulin release from pancreatic beta cells.
