WebIonotropic receptors act directly and are for rapid short-lived responses. They are usually part of an ion channel and when the neurotransmitter binds the receptor it responds by opening ion channels. As for Metabotropic receptors they act indirectly and cause a slower, longer lasting response.

Fast inhibitory transmission in the brain is mediated mostly by ionotropic GABA A receptors (GABA A Rs), but their essential components for synaptic localization remain unknown.

WebAlthough all acetylcholine receptors, by definition, respond to acetylcholine, they respond to other molecules as well. Nicotinic acetylcholine receptors ( nAChR, also known as "ionotropic" acetylcholine receptors) are … WebThere are two basic classes of receptors, ionotropic and metabotropic. These are activated by ligands -- transmitters. Thus, they are ligand gated. The ionotropic receptor forms a channel become permeable when the receptor is activated by its respective transmitter. When inactive, it is impermeable to ions.
