Kev piav qhia: Lawv pab cov molecules thoob plaws lub daim nyias nyias ntawm passive thauj , tus txheej txheem hu ua facilitated diffusion. Cov no proteins yog lub luag hauj lwm rau nqa ions thiab lwm yam me me molecules rau hauv lub cell.
Yog li ntawd, vim li cas cov proteins xav tau nyob rau hauv lub cell membrane?
Membrane proteins yog tseem ceeb rau kev thauj cov khoom hla mus cell membrane . Lawv tuaj yeem ua haujlwm ua enzymes lossis receptors. Nyob rau sab ntawm cov kua dej extracellular ntawm a cell membrane , koj pom cov carbohydrates. Lawv pab a cell kom pom tau tias yog ib yam ntawm cell thiab yog tseem ceeb rau tuav hlwb ua ke.
Tsis tas li ntawd, peb hom thauj proteins yog dab tsi? Channel cov proteins , ua tsaug channel cov proteins , thiab carrier cov proteins yog peb hom thauj proteins uas koom nrog hauv kev yooj yim diffusion. Ib channel protein ntau , a hom thauj protein , ua zoo li lub pore nyob rau hauv daim nyias nyias uas cia cov dej molecules los yog me me ions los ntawm sai sai.
Tsis tas li ntawd nug, ua li cas cov proteins txav mus thoob lub cell membrane?
Proteins hauv tus Membrane Kev thauj mus los feem ntau tshwm sim hla lub cell membrane . Lawv yog tso chaw mus hla tus daim nyias nyias yog li ib feem yog ntawm nyob rau hauv lub cell thiab ib feem yog ntawm sab nraud. Tsuas yog thaum lawv ntoo khaub lig tus bilayer yog lawv muaj peev xwm txav mus molecules thiab ions hauv thiab tawm ntawm cell.
Vim li cas thauj cov proteins xav tau lub zog?
Active kev thauj yog kev txav ntawm cov ntaub ntawv los ntawm lub cell membrane siv cell membrane siv cellular zog . thauj cov protein yuav tsum muaj zog ua haujlwm vim nws xav tau zog ces passive thauj uas xav tau tsis muaj zog tag nrho.

Yuav ua li cas ions thauj mus los ntawm cov cell membrane?
Cov molecules thiab ions txav spontaneously cia lawv cov concentration gradient (piv txwv li, los ntawm ib cheeb tsam ntawm siab dua mus rau ib cheeb tsam ntawm qis concentration) los ntawm diffusion. Molecules thiab ions tuaj yeem txav mus rau lawv cov concentration gradient, tab sis cov txheej txheem no, hu ua kev thauj mus los, yuav tsum tau siv lub zog (feem ntau los ntawm ATP)
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
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
Vim li cas cov neeg caij tsheb yuav tsum tau pab los ntawm cov cab kuj molecule?
Vim li cas cov neeg caij tsheb yuav tsum tau pab los ntawm cov cab kuj molecule? Cov neeg caij tsheb molecules xav tau kev pab vim lawv tsis tuaj yeem haum los ntawm cov cell membrane. Yooj yim diffusion nrog kev pab los ntawm cov cab kuj molecule tsis xav tau lub zog, nws mus los ntawm ntau dua concentration mus rau qis concentration
