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.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib txawv ntawm qhov sib txawv ntawm 97 yog dab tsi?
Teb thiab piav qhia: 9/7 x lub reciprocal = 1. 1 / 9/7 = reciprocal
Dab tsi yog qhov txawv ntawm voltage gated channels thiab ligand gated channels?
Voltage gated ion channels qhib nyob rau hauv teb rau voltage (piv txwv li thaum lub cell tau txais depolarized) qhov twg li ligand gated channels qhib nyob rau hauv teb rau ib tug ligand (qee yam tshuaj teeb liab) khi rau lawv. Lub ligand gated channels qhib thiab tso cai rau influx ntawm sodium, uas depolarizes cell
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
