The blood glucose lowering effect of insulin occurs when the molecules facilitate the uptake of glucose by binding to insulin receptors on muscle and fat cells - and simultaneously inhibit the output of glucose from the liver.
Insulins blodglucosenedsættende virkning indtræder, når molekylerne faciliterer optagelsen af glucose ved at binde sig til insulinreceptorer i muskel - og fedtceller og samtidig hæmmer leverens glucoseudskillelse.
