Ionotropic receptors act very quickly. As soon as a ligand binds to them, they change shape and allow ions to flow in. But the ligand doesn’t stay in place very long, and the channel closes back very quickly. Metabotropic receptors, on the other hand, take a little longer “to do anything” depending … Meer weergeven Ionotropic receptors are transmembrane molecules that can “open” or “close” a channel that would allow smaller particles to travel in and out of the cell. As the name implies, … Meer weergeven Metabotropic receptors do not have a “channel” that opens or closes. Instead, they are linked to another small chemical called a “G-protein.” As soon as a ligand binds the metabotropic receptor, the receptor … Meer weergeven If you want more articles and videos about the Nervous System, you can find them here.
