The primary advantage of G-protein-coupled receptors over ionotropic receptors is that they:

Question

Quizplus · Accepted Answer

G-protein-coupled receptors amplify cellular signal by initiating a cascade of intracellular events through the activation of second messengers. In contrast, ionotropic receptors directly open ion channels, leading to a faster response, but without the ability to amplify signals. Thus, G-protein-coupled receptors have the advantage of mediating a more diverse range of cellular responses by activating multiple signaling pathways. They do not enhance cellular metabolism or inhibit the formation of second messengers, as these are functions of other cellular processes.
