Qhov no txhais tau hais tias sab hauv ntawm lub xov tooj ntawm tes yog qhov tsis zoo uas cuam tshuam rau sab nraud. Hyperpolarization yog thaum daim nyias nyias muaj peev xwm dhau los ua qhov tsis zoo ntawm ib qho chaw tshwj xeeb ntawm cov neuron daim nyias nyias, thaum depolarization yog thaum cov membrane muaj peev xwm ua tsis zoo (ntau qhov zoo).
Yuav ua li cas thaum lub sijhawm hyperpolarization ntawm lub cell?
Hyperpolarization yog ib qho kev hloov pauv ntawm lub cell daim nyias nyias uas ua rau nws tsis zoo. Nws yog qhov opposite ntawm ib tug depolarization. Nws inhibits kev muaj peev xwm ua tau los ntawm kev ua kom lub zog xav tau kom txav cov membrane muaj peev xwm mus rau qhov ua tau zoo.
txhais li cas rau lub cell kom hyperpolarized?
Lub Ib Hlis 12, 2021 / Guest User. kev txav ntawm lub cell daim nyias nyias muaj peev xwm mus rau qhov tsis zoo ntau dua (piv txwv li, txav deb ntawm xoom). Thaum ib tug neuron yog hyperpolarized, nws tsis tshua muaj peev xwm tua hluav taws.
Cov channel twg qhib thaum lub sijhawm hyperpolarization?
On hyperpolarization, HCN channels qhib thiab nqa ib Na+ sab hauv tam sim no uas tig mus depolarizes ntawm tes. Lawv yog modulated los ntawm cyclic nucleotides, thiab yog li, ob peb tus neeg xa xov liaison thib ob qhia rau hluav taws xob ua haujlwm (4). HCN channels, tseem hu ua pacemaker channels, ua haujlwm ntau yam.
Yuav ua li cas thaum lub cell Depolarizes?
Hauv biology, depolarization (Lus Askiv Askiv: Depolarisation) yog kev hloov pauv hauv ib lub xovtooj ntawm tes, thaum lub sijhawm ntawd lub xovtooj tau txais kev hloov pauv hauv kev faib hluav taws xob, ua rau cov nqi tsis zoo hauv lub xovtooj piv rau sab nraud.
