| Front | What is the role of glucagon? |
|---|---|
| Back | Produced by the alpha-cells of the islets of Langerhans in the pancreas. If blood glucose concentrations are too low, the alpha-cells will detect this fall and secrete glucagon directly into the bloodstream. Unlike insulin, the only cells in the body which have glucagon receptors are the liver and fat cells. Therefore these are the only cells that can respond to glucagon. |
