Yooj yim diffusion los yog uniport yog qhov yooj yim tshaj plaws ntawm passive carrier-mediated thauj thiab ua rau kev hloov ntawm hydrophilic molecules loj nyob rau hauv lub cell membrane. Cotransport lossis symport yog ib hom kev thauj mus los thib ob.

Tom qab ntawd, ib tus tuaj yeem nug, puas yog kev thauj khoom loj lossis tsis ua haujlwm?

Zoo li cov txheej txheem thauj khoom nquag uas txav ions thiab cov molecules me ntawm cov khoom thauj khoom thauj, kev thauj khoom loj yog qhov xav tau lub zog (thiab, qhov tseeb, lub zog siv zog) txheej txheem. Ntawm no, peb yuav saib ntau hom kev thauj khoom loj: phagocytosis , pinocytosis, receptor-mediated endocytosis thiab exocytosis.

Peb hom kev thauj mus los nruab nrab yog dab tsi? Muaj peb hom ntawm nruab nrab thauj : uniport, symport, thiab antiport. Tej yam uas yuav ua tau thauj yog cov as-ham, ions, qabzib, thiab lwm yam, txhua yam nyob ntawm qhov xav tau ntawm cov cell.

Ib yam li ntawd, puas yog diffusion nquag lossis passive?

Cov txheej txheem no hu ua passive thauj los yog yooj yim diffusion , thiab tsis xav tau lub zog. Lub solute tuaj yeem txav mus "nce toj," los ntawm thaj chaw qis dua mus rau siab dua. Cov txheej txheem no hu ua kev thauj mus los , thiab yuav tsum muaj qee hom tshuaj muaj zog.

Puas yog osmosis passive lossis active?

osmosis yog cov txheej txheem uas cov dej molecules txav los ntawm ib cheeb tsam ntawm cov dej muaj peev xwm ntau dua mus rau thaj tsam ntawm qhov muaj peev xwm qis qis hauv cov dej muaj peev xwm gradient hla ib feem permeable membrane, yog li lub zog me me yuav tsum tau ua kom tiav cov txheej txheem no, yog li nws yog ib daim ntawv lossis passive thauj.
