Ionotropic receptors . Ionotropic receptors yog ib qho membrane-spanning proteins, nrog ntau hom subunit uas pab pawg ua ke los tsim ib qho ion channel thiab nws cov kab ligand-binding sites. Ib piv txwv yog nicotinic ACh tus txais (nCaR) (Fig.

Raws li, tus ionotropic receptor ua dab tsi?

Ionotropic receptors yog membrane-bound receptors cov proteins uas teb rau ligand kev khi los ntawm kev qhib lub ion channel thiab tso cov ions ntws mus rau hauv ntawm tes , txawm tias nce lossis txo qhov yuav tshwm sim uas qhov kev ua haujlwm yuav raug tua.

Ib yam li ntawd, qhov txawv ntawm metabotropic thiab ionotropic yog dab tsi? Ionotropic receptors hloov cov duab thaum lawv raug khi los ntawm ligand. Qhov kev hloov pauv hauv cov duab no tsim cov channel uas tso cai rau ions ntws los ntawm. Metabotropic receptors tsis muaj cov channel. Metabotropic receptors qhib G-protein uas nyob rau hauv lem qhib lub thib ob xa xov, uas nyob rau hauv lem yuav qhib lwm yam.

Ib yam li ntawd, nyob qhov twg ionotropic receptors pom?

Nws yuav yog nyob ntawm qhov chaw ntawm tes lossis hauv vesicles. Raws li lawv cov yam ntxwv thiab ua haujlwm yam ntxwv, tus neeg xa xov paj hlwb tus txais tuaj yeem muab faib ua ob pawg dav: metabotropic thiab ionotropic receptors . Ionotropic receptors tsim ib qho ion channel pore.

Dab tsi yog postsynaptic receptor?

postsynaptic receptor . ib yam tus txais uas nyob ntawm daim nyias nyias ntawm tes lossis sab hauv ntawm a postsynaptic hlwb.
