Vim li cas ua tus Cov neeg caij tsheb molecules yuav tsum tau pab los ntawm cov cab kuj molecule ? Cov cov neeg caij tsheb molecules xav tau kev pab vim lawv ua tau tsis haum los ntawm lub cell membrane. Facilitated diffusion nrog cov pab ntawm a carrier molecule ua tsis xav tau lub zog, nws yog mus los ntawm siab dua concentration mus rau qis concentration.
Kuj tseem paub yog, dab tsi yog cov cab kuj molecules xav tau rau?
A molecule uas plays lub luag hauj lwm nyob rau hauv thauj electrons los ntawm lub electron thauj saw. Carrier molecules feem ntau yog cov proteins khi rau ib pawg tsis muaj protein; lawv muaj peev xwm undergo oxidation thiab txo kuj yooj yim, yog li cia electrons ntws los ntawm lub system.
Tsis tas li ntawd, cov cab kuj puas xav tau lub zog? Active thauj carrier proteins xav tau lub zog txav cov tshuaj tiv thaiv lawv cov concentration gradient. Qhov ntawd zog yuav tuaj nyob rau hauv daim ntawv ntawm ATP uas yog siv los ntawm lub carrier protein ncaj qha, los yog siv tau zog los ntawm lwm qhov chaw. Tab sis lub carrier protein tsis siv ATP ncaj qha.
Kuj tseem xav paub, vim li cas ho tsis xav tau lub zog rau cov neeg caij tsheb molecule nqa hla lub cell membrane los ntawm cov cab kuj molecule?
Tsis tas yuav muaj zog vim hais tias cov hais yog txav los ntawm ib cheeb tsam ntawm siab dua concentration mus rau ib cheeb tsam ntawm qis concentration.
Yuav ua li cas yog ib tug carrier protein quizlet?
carrier protein . Cov protein uas hloov cov duab tso cai rau ib yam khoom mus rau hauv lub plasma membrane. phagocytosis. lub engulfing ntawm cov zaub mov los ntawm ib tug cell. yooj yim diffusion.

Yuav ua li cas yog ib tug piv txwv ntawm ib tug electron cab kuj?
Raws li cov electrons raug xa mus los ntawm ib lub tshuab nqa hluav taws xob mus rau lwm qhov, lawv lub zog theem qis, thiab lub zog tawm. Cytochromes thiab quinones (xws li coenzyme Q) yog qee qhov piv txwv ntawm cov khoom siv hluav taws xob
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Vim li cas koj thiaj li yuav tsum tau siv lub hauv paus ntsiab lus los saib cov Substages ntawm mitosis?
Cov lus qhia hauv paus dos feem ntau siv los kawm txog mitosis. Lawv yog cov chaw ntawm kev loj hlob sai, yog li cov hlwb tau faib sai
Dab tsi yog tus cab kuj ntawm cov khoom siv caj ces?
DNA yog replicated thiab xa mus rau lwm tiam neeg kom lub hlwb ua tau tib yam dej num raws li cov niam txiv ntawm tes. Yog li, DNA uas code rau noob yog suav hais tias yog tus nqa khoom ntawm cov ntaub ntawv caj ces hauv feem ntau ntawm cov kab mob nyob
Dab tsi cov cab kuj muaj protein pab hauv kev yooj yim diffusion?
Channel proteins, gated channel proteins, thiab carrier proteins yog peb hom thauj cov proteins uas koom nrog hauv kev yooj yim diffusion. Cov protein channel, ib hom thauj protein, ua zoo li lub pore hauv daim nyias nyias uas cia cov dej molecules los yog cov ions me me dhau los sai
