GCSE Biology - Regulating Glucose | Glucose & Glycogen & Glucagon | Blood Glucose Graphs

⭐️ https://www.cognito.org/ ⭐️

** WHAT'S COVERED **
1. Blood Glucose Concentration Regulation
The need to maintain blood glucose within a specific range.
The concept of homeostasis and negative feedback.
2. Role of Insulin
Released by the pancreas when blood glucose is high.
Stimulates cells (especially liver and muscle) to take up glucose.
Promotes the conversion of glucose to glycogen for storage.
3. Role of Glucagon
Released by the pancreas when blood glucose is low.
Stimulates the liver to break down glycogen into glucose.
Promotes the release of glucose into the bloodstream.
4. Interaction between Insulin and Glucagon
How these hormones work antagonistically.
Maintaining blood glucose levels through a negative feedback loop.
