Study Notes
Hormone Regulation of Blood Glucose
- Glucagon is responsible for increasing blood glucose levels.
Insulin and Glucagon Synthesis
- Insulin and glucagon are synthesized in the islets of Langerhans, located in the pancreas.
Islets of Langerhans
- The main function of the islets of Langerhans is to produce and regulate hormones that control blood sugar levels.
Insulin Function
- Insulin binds to receptors on the surface of target cells, particularly in the liver and muscle cells, to facilitate glucose uptake.
Glucagon Function
- The main function of glucagon is to stimulate the liver to break down stored glycogen into glucose, which is then released into the bloodstream to increase blood sugar levels.
