The three main types of cell surface receptors are ion-channel-coupled receptors, G-protein-coupled receptors, and enzyme-couple receptors. They are all capable of binding extracellular signaling molecules but differ in how they relay that signal across the membrane. How does each type of surface receptor relay signal?

What do both G protein-coupled receptors and tyrosine kinase receptors have in common? The binding site for the signaling molecule is located on the outside of the cell. They both interact with G proteins. Binding of the signaling molecule forms a dimer. They both result in a phosphorylation cascade.

Upon binding of a ligand, G-protein-coupled receptors do which of the following? Select one: a. The G-protein exchanges a GDP for a GTP, and the alpha subunit detaches from the beta/gamma complex b. They dimerize, autophosphorylate, and trigger a cascade in intracellular signal transduction/phosphorylation c. They migrate to the nucleus to activate/repress specific genes d. They get internalized and start producing cAMP e. They induce apoptosis
