Muaj peb lub ntsiab hom ntawm ion cov channel i.e. voltage- rooj vag , extracellular ligand- rooj vag thiab intracellular ligand- rooj vag nrog rau ob pawg ntawm lwm yam ion cov channel.

Kuj paub, 3 hom ion channel yog dab tsi?

Raws li qhov stimulus uas lawv teb, ion channels muab faib ua peb superfamilies: voltage-gated, ligand-gated thiab mechano-sensitive ion channels.

Ib yam li ntawd, dab tsi yog qhov tshwj xeeb ntawm gated channels? gated channel . Ib ion channel nyob rau hauv ib lub cell membrane uas qhib los yog kaw nyob rau hauv lub teb rau ib tug stimulus xws li ib tug neurotransmitter los yog hloov nyob rau hauv siab, voltage, los yog lub teeb. Saib ntxiv: channel.

Yog li ntawd, peb hom ion tseem ceeb yog dab tsi thiab lawv txawv li cas?

Ntau hom ion channel tau piav qhia: cov channel teb rau hluav taws xob (voltage-dependent ion channels ), mechanical, lossis chemical (ligand-gated ion channels ) stimuli; ion channels tswj los ntawm phosphorylation / dephosphorylation mechanisms; thiab G protein-gated ion channels.

Dab tsi yog qhov tseem ceeb thiab hom ion channels?

Ligand-gated ion channels yog tseem ceeb , vim lawv ntseeg tias yog lub hom phiaj rau ntau cov tshuaj siv los kho cov kab mob, xws li kev nyuaj siab, kev ntxhov siab, mob vwm, Alzheimer's disease, Schizophrenia, thiab Autism.
