Nettet1. jan. 1974 · Insulin affects transport in cell membranes (fat cell “ghosts”) in the virtual absence of cytoplasm and cell organelles (Rodbell, 1966; Carter and Martin, 1969). At this point in time was may view the action of insulin as follows: 1. The hormone affects only those cells which possess a specific receptor in their membrane. 2. NettetInsulin initiates its action by binding to a glycoprotein receptor on the surface of the cell. This receptor consists of an alpha-subunit, which binds the hormone, and a beta …

Insulin acts via specific membrane-bound receptors on target tissues to regulate metabolism of carbohydrate, protein, and fats. Target organs for insulin include the liver, skeletal muscle, and adipose tissue. Within the liver, insulin stimulates hepatic glycogen synthesis.
