Which of the following statements best describes the mechanism of action of insulin on target cells?
AInsulin binds to a receptor on the outer surface of the plasma membrane, activating adenylate cyclase through the Gs protein.
BInsulin binds to a cytoplasmic receptor and is transferred as a hormone receptor complex to the nucleus to modulate gene expression.
CInsulin enters the cell and causes the release of calcium ions from intracellular stores.
DInsulin binds to a transmembrane receptor on the outer surface of the plasma membrane, activating the tyrosine kinase in the cytosolic domain of the receptor.
