Kev thauj mus los nruab nrab hais txog thauj nruab nrab los ntawm ib daim nyias nyias thauj protein ntau. Nws yog ib qho uniport system vim hais tias nws tshwj xeeb thauj cov piam thaj hauv ib qho kev taw qhia, cia nws cov concentration gradient hla cov cell membrane.

Tsis tas li ntawd, tus neeg nqa khoom nruab nrab thauj khoom yog dab tsi?

Tus neeg nqa khoom - Kev Thauj Mus Los Mechanisms A. Facilitated Diffusion Facilitated diffusion lossis uniport yog daim ntawv yooj yim tshaj plaws ntawm tus cab kuj - nruab nrab thauj thiab ua rau kev hloov pauv ntawm cov hydrophilic molecules loj (qab zib, amino acids, nu-cleotides, thiab organic acids thiab bases) thoob plaws cell membrane.

Ib yam li ntawd, yog Channel mediated diffusion active lossis passive? Facilitated diffusion (tseem hu ua yooj yim thauj los yog passive-mediated thauj ) yog tus txheej txheem ntawm spontaneous passive thauj (as opposed to kev thauj mus los ) ntawm cov molecules los yog ions hla ib daim nyias nyias ntawm ib qho transmembrane integral proteins.

Tsis tas li ntawd nug, Channel mediated txhawb kev nthuav dav yog dab tsi?

Channel - Kev sib haum xeeb Facilitated Diffusion . Hom ntawm Diffusion uas siv cov channel los tswj cov dej ntws ntawm ions thiab lwm yam molecules los ntawm lub cell membrane.

Dab tsi yog qhov txawv ntawm kev thauj mus los thiab cov channel?

- TRANSPORTERS : Hloov cov organic molecules me me los yog inorganic ions los ntawm ib sab ntawm daim nyias nyias mus rau lwm qhov los ntawm HLOOV SHAPE. - CHANNELS : tsim me me HYDROPHILIC PORES hla lub membrane los ntawm cov khoom no tuaj yeem dhau los ntawm DFFUSION.
