Lawv muaj cov nyhuv ntev dua li ionotropic receptors, uas qhib sai sai tab sis tsuas yog qhib rau ob peb milliseconds. Thaum ionotropic channels muaj cov nyhuv tsuas yog nyob rau hauv lub tam sim ntawd cheeb tsam ntawm lub receptor, cov teebmeem ntawm metabotropic tshuaj receptors tuaj yeem nthuav dav thoob plaws hauv lub cell.
Yog 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 sab saum toj no, puas yog Serotonin ionotropic lossis metabotropic? Hloov pauv, nws tau xav tias, nrog rau ib qho kev zam, monoamines (dopamine, serotonin , thiab norepinephrine) teeb liab ntawm metabotropic tshuaj receptors. Ionotropic receptors tau teev rau ntau ligands-tab sis tsuas yog rau 5-HT3 receptor, txawm li cas los xij, tsis muaj nyob rau monoamines.
Ua kom pom qhov no, Metabotropic txhais li cas?
Kev kho mob Txhais ntawm metabotropic tshuaj : cuam tshuam nrog lossis ua tus neeg txais khoom rau glutamate uas thaum sib xyaw nrog G protein ua rau nce ntxiv ntawm qee cov neeg xa xov hauv lub cev metabotropic tshuaj glutamate receptors.
Vim li cas cov ionotropic receptors ua haujlwm sai?
a Ionotropic Receptor Transmission LGCs yog ceev teeb liab cov receptors (millisecond latency) vim yog kev sib txuas ncaj qha ntawm tus neeg txais kev pab qhib thiab qhib channel. Muaj thiab ceev teb cov lus teb vim hais tias cov tshuaj xa xov sai sai dissociates los ntawm tus neeg txais kev pab , ib kev ua uas kaw cov channel.

Puas yog macular degeneration tshwm sim sai sai?
Cov tsos mob ntub dej macular degeneration feem ntau tshwm sim sai sai thiab zuj zus sai. Tej zaum lawv yuav suav nrog: Qhov muag tsis pom kev, xws li cov kab ncaj zoo li khoov. Pib sai sai thiab ua rau cov tsos mob hnyav zuj zus
Puas yog nws zoo dua kom nce lossis txo lub teeb thaum hloov mus rau qhov loj dua?
Puas yog qhov xav tau ntau ntxiv lossis txo lub teeb thaum hloov mus rau qhov ua kom siab dua? Ua kom lub teeb pom kev ntxiv vim tias lub hom phiaj qhib qhov muag tsawg zuj zus nrog kev nthuav dav, tso lub teeb kom tsawg
Puas muaj kev kho sai sai rau hemophilia?
Tam sim no tsis muaj kev kho rau hemophilia, tab sis cov neeg mob tuaj yeem kho nrog kev tso ntshav khov. “Cov tshuaj tiv thaiv no tuaj yeem ua rau cov protein tsis zoo uas nws yuav tsis kho lossis tiv thaiv lawv los ntshav. Qhov no tshwm sim txog li 30 feem pua lossis ntau dua ntawm cov neeg mob hemophilia A (yam tsis txaus VIII tsis txaus)
Dab tsi yog lo lus rau ib tus neeg muaj tshuaj lom uas ua rau muaj kev puas tsuaj lossis kev yug me nyuam hauv lub fetus lossis embryo?
Teratology. Teratogens yog cov khoom uas yuav ua rau yug me nyuam tsis xws luag los ntawm kev cuam tshuam rau embryo lossis fetus
Dab tsi yog qhov txawv ntawm metabotropic thiab ionotropic receptors?
Ionotropic thiab metabotropic receptors yog ob leeg ligand-gated transmembrane proteins. 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
