Insulins blodglukosenedsættende virkning indtræder, når molekylerne letter optagelsen af glukose ved at binde sig til insulinreceptorer i muskel - og fedtceller og samtidig hæmmer leverens glukoseudskillelse.
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.
