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.
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.
