Thaum nquag kev thauj mus los xav tau lub zog thiab ua haujlwm, passive thauj tsis tau. Muaj ntau ntau yam ntawm no yooj yim txav ntawm molecules. Nws tuaj yeem ua tau yooj yim li cov molecules txav dawb xws li osmosis lossis nthuav tawm . Qee zaum, cov proteins yog siv los pab txav cov molecules sai dua.
Hauv qhov no, vim li cas diffusion yog ib qho piv txwv ntawm kev thauj mus los?
Ib piv txwv ntawm passive thauj yog nthuav tawm , thaum molecules txav los ntawm ib cheeb tsam ntawm siab concentration (loj ntau) mus rau ib cheeb tsam ntawm tsawg concentration (tsawg npaum). Molecules tau hais tias ib txwm ntws los ntawm lawv cov concentration gradient. Oxygen yog ib qho molecule uas muaj peev xwm nthuav tawm thoob plaws lub cell membrane.
Kuj Paub, osmosis diffusion thiab active thauj yog dab tsi? Osmosis yog qhov txav ntawm cov dej hauv qhov concentration gradient (los ntawm siab mus rau qis concentration) hla ib feem permeable membrane. Kev thauj mus los yog lub zog ntawm yaj solutes hla ib daim nyias nyias tawm tsam qhov concentration gradient (tsiv los ntawm qis mus rau siab concentration).
Tib neeg kuj nug, 4 hom kev thauj mus los yog dab tsi?
Tus nqi ntawm passive thauj nyob ntawm qhov permeability ntawm cell membrane, uas, nyob rau hauv lem, nyob ntawm lub koom haum thiab yam ntxwv ntawm daim nyias nyias lipid thiab proteins. Plaub yam tseem ceeb ntawm kev thauj mus los yog qhov yooj yim diffusion, yooj yim diffusion, lim , thiab/los yog osmosis.
Qhov kev txav twg yog cov txheej txheem passive?
Passive kev thauj mus los yog ib qho tshwm sim tshwm sim thiab tsis xav kom lub cell siv lub zog los ua kom tiav kev txav mus los . Hauv passive kev thauj mus los, cov khoom txav los ntawm thaj chaw siab dua mus rau thaj tsam ntawm qis dua concentration hauv a txheej txheem npe diffusion.

Kev hloov pauv kev hloov pauv tshiab tau siv dav hauv ntau lub ntsiab lus
Dab tsi yog osmosis thiab diffusion hauv hlwb?
Diffusion yog ib qho kev txav txav ntawm cov khoom los ntawm thaj chaw siab concentration mus rau thaj tsam ntawm qhov tsis tshua muaj siab. Osmosis yog qhov tshwm sim ntawm cov dej txav ntawm cov dej hla ib lub semipermeable daim nyias nyias los ntawm thaj tsam ntawm cov kua qaub qis mus rau cov tshuaj ntau dua, nce qhov concentration gradient
Puas yog osmosis diffusion active lossis passive?
Nco tseg: diffusion thiab osmosis yog ob qho tib si passive, piv txwv li lub zog los ntawm ATP tsis siv. Ib feem permeable membrane yog ib qho kev thaiv uas tso cai rau kev nkag mus ntawm qee yam khoom tab sis tsis yog lwm tus; Nws tso cai rau kev nkag mus ntawm cov kuab tshuaj molecules tab sis tsis yog qee qhov loj dua solute molecules
