Passive mechanisms zoo li diffusion siv tsis muaj zog, thaum nquag thaujxav tau lub zog kom ua tiav.
hom kev thauj twg yuav tsum muaj zog?
Thaum lub sijhawm thauj mus los, cov khoom txav tawm tsam qhov concentration gradient, los ntawm thaj tsam qis mus rau thaj tsam siab. Cov txheej txheem no yog "active" vim hais tias nws yuav tsum tau siv lub zog (feem ntau nyob rau hauv daim ntawv ntawm ATP). Nws yog qhov opposite of passive transport.
Qhov twg ntawm cov txheej txheem thauj khoom hauv qab no yuav tsum muaj lub zog?
Kev thauj mus los zoo li diffusion, yooj yim diffusion thiab osmosis tsis xav tau lub zog. Kev thauj mus los zoo li phagocytosis, exocytosis, xav tau lub zog.
Yuav ua li cas yuav tsum muaj lub zog exocytosis diffusion ntawm oxygen mus rau hauv cov ntshav liab diffusion ntawm ions los ntawm cov poov tshuaj channel osmosis?
Teb Chaws Tus Kws Tshaj Lij Tshaj Lij
Cov lus teb yog exocytosis. Exocytosis yog tus txheej txheem rov qab rau endocytosis. Hauv exocytosis, cell thauj cov molecules, xws li cov protein, tawm ntawm lub cell thiab cov txheej txheem no yuav tsum muaj zog.
hom molecular txav yuav tsum muaj zog?
Qee lub molecules txawm xav tau lub zog nkag los pab kom lawv hla cov cell membrane. Kev txav ntawm cov molecules hla ib daim nyias nyias uas tsis muaj lub zog nkag mus yog hu ua passive thauj. Thaum lub zog (ATP) xav tau, lub zog yog hu ua nquag thauj.
