Question

Describe the mechanism of action of insulin.

Answer 1

insulin helps to body to use glucose from carbohydrates and store it for future use.

Answer 2

Insulin 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-subunit, which is an insulin-stimulated, tyrosine-specific protein kinase. Activation of this kinase is believed to generate a signal that eventually results in insulin's action on glucose, lipid, and protein metabolism.
