Flashcards
Muscarinic receptors
Muscarinic receptors
A type of acetylcholine receptor that is G protein-coupled, meaning it uses signal transduction pathways to elicit cellular changes.
Ligand-gated ion channel
Ligand-gated ion channel
A type of receptor that opens an ion channel when a specific molecule binds to it.
Nicotinic receptors
Nicotinic receptors
A type of acetylcholine receptor that is a ligand-gated ion channel, directly opening an ion channel upon binding acetylcholine.
