WebMar 29, 2024 · However, the actions of insulin and glucagon in carbohydrate metabolism are opposite. Furthermore, insulin and glucagon have various physiologic roles in addition to the regulation of carbohydrate metabolism. The physiologic effects of insulin and glucagon on the cell are initiated by the binding of each hormone to target cell receptors. WebInsulin secretion by the β cells of the islets of Langerhans is primarily regulated by the d-glucose level in the extracellular fluid bathing the β cells. Glucagon increases and somatostatin decreases insulin release via paracrine actions. Insulin release is stimulated by GH, cortisol, PRL, and the gonadal steroids. It is decreased by PTH.

Beta cells in the islets of Langerhans release insulin in two phases. The first-phase release is rapidly triggered in response to increased blood glucose levels, and lasts about 10 minutes. The second phase is a sustained, slow release of newly formed vesicles triggered independently of sugar, peaking in 2 to 3 hours. The two phases of the insulin release suggest that insulin granules are presen…
