Nicotinic acetylcholine receptors (nAChR, tseem hu ua "ionotropic" acetylcholine receptors) tshwj xeeb tshaj yog teb rau nicotine. Cov nicotine ACh receptor kuj yog Na+, K+ thiab Ca2 + ion channel.
Puas yog muscarinic Ach receptors ionotropic?
Cholinergic receptors tau muab faib ua G protein-coupled (metabotropic) receptors (muscarinic subtype) thiab ion channel (ionotropic) receptors (cov nicotinic subtype).
Qhov twg ntawm cov receptors hauv qab no yog ionotropic?
GABA Receptors Cov no yog cov tseem ceeb ionotropic receptors tam sim no hauv CNS. Lawv yog cov tseem ceeb inhibitory receptors hauv CNS. Lawv yog tsim los ntawm tsib subunits. Kev khi ntawm GABA neurotransmitter rau ib qho ntawm cov subunit ua rau qhib cov ion channel.
Dab tsi yog ob hom acetylcholine receptors?
Tus acetylcholine receptor (AChR) yog cov protein ua membrane uas khi rau cov neurotransmitter acetylcholine (Ach). Cov receptors no tuaj yeem muab faib ua ob hom tseem ceeb ntawm cov receptors, nicotinic thiab muscarinic.
Puas yog nicotinic acetylcholine receptors ligand-gated ion channels?
Nicotinic acetylcholine receptors (nAChRs) yog ligand-gated ion channels thiab tuaj yeem muab faib ua ob pawg: cov leeg receptors, uas pom nyob rau ntawm pob txha neuromuscular hlws ris qhov chaw uas lawv khoneuromuscular kis tau tus mob, thiab neuronal receptors, uas muaj nyob thoob plaws hauv lub peripheral thiab hauv nruab nrab lub paj hlwb…
