Receptor proteins that indirectly open or close ion channels through the activation of a second messenger are referred to as ________ receptors.

Question

Quizplus · Accepted Answer

Metabotropic receptors activate a second messenger system, which in turn opens or closes ion channels. Ionotropic receptors, on the other hand, directly open or close ion channels upon binding with a ligand. Postsynaptic and presynaptic are descriptions of the location of a receptor in relation to a synapse and are not directly related to the mechanism of ion channel opening or closing.
