Thauj cov proteins ua qhov rooj rau lub cell , pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua tus neeg nyob cell . Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration.

Tsis tas li ntawd, cov proteins thauj khoom siv rau dab tsi?

A thauj protein (ntau lub npe hu ua lub twj tso kua mis transmembrane, transporter, escort protein ntau , kua qaub thauj protein , cation thauj protein , los yog anion thauj protein ) yog a protein ntau uas ua haujlwm ntawm kev txav mus rau lwm yam khoom hauv lub cev.

Ib tug kuj yuav nug, dab tsi yog peb lub luag haujlwm ntawm membrane proteins? Membrane proteins tuaj yeem ua haujlwm ntau yam ntawm tus yuam sij muaj nuj nqi : Junctions – Pab kom txuas thiab koom ob lub hlwb ua ke. Enzymes - Kho rau daim nyias nyias localises metabolic txoj kev. Tsheb thauj mus los - Lub luag haujlwm rau kev nthuav dav thiab kev thauj mus los.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog hom kev thauj cov protein sib txawv?

thauj cov protein feem ntau ua ob hom kev thauj mus los : “facilitated diffusion,” qhov twg a thauj protein tsuas yog tsim kom muaj qhov qhib rau cov khoom kom diffuse cia nws cov concentration gradient; thiab “active thauj ,” qhov twg lub cell siv lub zog thiaj li txav tau cov khoom tawm tsam nws cov concentration gradient.

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.
