Web8 feb. 2024 · Your immune system attacks and destroys beta cells in the pancreas that make insulin. Type 2 diabetes can affect adults or children. It’s a progressive disease, meaning that it happens over time. WebInsulin is released in response to high blood glucose concentrations. High blood glucose concentrations means glucose is taken up by the beta-cells in the Islet's of Langerhans and is respired to produce ATP. This ATP then blocks ATP-sensitive potassium ion channels resulting in their closure.
Web27 okt. 2009 · When released from the pancreas, insulin helps other cells in the body take up sugar from the bloodstream, feeding the cells and bringing blood sugar levels down again. Diabetes, in its several forms, arises when the system goes awry. Before its release, insulin is stored in beta cells in secretory granules.
