Kev thauj mus los 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.

Raws li, cov proteins channel puas xav tau lub zog?

Channel Protein Thauj Cov txheej txheem uas molecules dhau los ntawm ib daim nyias nyias ntawm a channel protein hu ua carrier-mediated transport. Muaj ob hom kev thauj uas siv channel proteins . Thawj hom ua tsis yog xav tau lub zog txav cov khoom hla lub cell membrane.

Ib yam li ntawd, 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.

Yog li ntawd, cov cab kuj muaj protein ntau active los yog passive?

Active Kev thauj mus los yog kev txav ntawm cov khoom hla ib daim nyias nyias tawm tsam nws cov concentration gradient. Tsis zoo li channel cov proteins uas tsuas yog thauj khoom los ntawm daim nyias nyias passively , carrier proteins tuaj yeem thauj ions thiab molecules ib yam nkaus passively los ntawm kev yooj yim diffusion, los yog ntawm theem nrab nquag thauj.

Yuav ua li cas molecules mus rau carrier proteins?

Lipophilic molecules, suav nrog me me, tsis muaj cov khoom siv molecules zoo li dej thiab oxygen, diffuse los ntawm daim nyias nyias. yooj yim diffusion down ib tug concentration gradient. Cov kws kho mob tshwj xeeb cov proteins pab txhawb rau nthuav tawm ntawm ntau molecules; lawv yog tshwj xeeb rau cov molecule thauj thiab txav mus rau ib tug concentration gradient.
