What are two basic functional distinctions between ionotropic receptors and metabotropic receptors?
What will be an ideal response?
Ionotropic (fast) receptors are directly linked to ion channels. Thus, receptor activation induces very rapid onset of actions on neurons, and, typically, a short-duration action. Metabotropic (slow) receptors work via their activation of secondary messenger systems within neurons, thus acting on ion channels indirectly. Metabotropic receptor activation induces effects relatively slowly and for a longer period of time than is generally the case with ionotropic receptors.
