Describe the common features shared by GPCRs and RTKs in their signaling mechanisms, focusing on how they are able to amplify signals. Specifically, how is the signal from one binding event (i.e., the binding of one ligand molecule to an individual receptor) propagated and strengthened? Describe one difference in how GPCRs and RTKs transform extracellular signals into intracellular responses.
