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

Yog li, yog osmosis Ib qho piv txwv ntawm kev thauj mus los?

Lwm qhov loj piv txwv ntawm passive thauj yog osmosis . Qhov no yog txheej txheem dej tshwj xeeb. Feem ntau, cov hlwb nyob hauv ib puag ncig uas muaj ib qho concentration ntawm ions sab nraud thiab ib qho sab hauv. Vim tias cov concentrations zoo ib yam, lub xovtooj ntawm tes tuaj yeem tso cov ions hauv ib qho tawm kom ciaj sia.

Tsis tas li, osmosis puas suav tias yog kev thauj mus los? Osmosis yog qhov diffusion ntawm cov dej molecules, nqes qhov concentration gradient, los ntawm ib feem permeable membrane. Kev thauj mus los yog qhov txav ntawm cov kuab tshuaj los ntawm thaj tsam ntawm qhov tsis tshua muaj siab mus rau siab concentratio thiaj li tiv thaiv cov concentration gradient.

Yog li ntawd, hom kev thauj mus los yog osmosis?

passive thauj

Hom kev thauj khoom twg yog passive?

Tus nqi ntawm kev thauj mus los yog nyob ntawm qhov permeability ntawm cov cell membrane, uas, nyob rau hauv lem, nyob ntawm lub koom haum thiab cov yam ntxwv ntawm daim nyias nyias lipids thiab cov proteins . Plaub yam tseem ceeb ntawm kev thauj mus los yog yooj yim diffusion, yooj yim diffusion, pom, thiab / lossis osmosis.
