Passive Thauj : Yooj yim Diffusion

Diffusion hla lub cell membrane yog ib hom passive thauj , los yog thauj hla lub cell membrane uas tsis xav tau lub zog. Molecules uas yog hydrophobic, ib yam li thaj av hydrophobic, tuaj yeem dhau los ntawm cov cell membrane los ntawm kev yooj yim. nthuav tawm

Ntawm no, yog Diffusion yog ib qho kev thauj mus los?

Thaum nquag thauj xav tau lub zog thiab ua haujlwm, passive thauj tsis. 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 . Txij li thaum lub cell membrane yuav tsis cia cov piam thaj hla los ntawm nthuav tawm , xav tau kev pab.

Tsis tas li ntawd, passive diffusion txhais li cas? Passive thauj yog tus nthuav tawm ntawm cov khoom hla ib daim nyias nyias. Qhov no yog tus txheej txheem spontaneous thiab cellular zog yog tsis siv nyiaj. Molecules yuav txav los ntawm qhov twg cov khoom yog ntau concentrated rau qhov twg nws yog tsawg concentrated.

Ces, uas yog ib tug passive thauj txheej txheem?

Passive thauj yog ib qho kev txav ntawm ions thiab lwm yam atomic los yog molecular tshuaj nyob rau hauv cell membranes yam tsis xav tau lub zog input. Plaub yam tseem ceeb ntawm passive thauj yog yooj yim diffusion, yooj yim diffusion, pom, thiab / los yog osmosis.

Dab tsi tau raug thauj hauv diffusion?

Dej, carbon dioxide, thiab oxygen yog ob peb yam yooj yim molecules uas yuav hla lub cell membrane los ntawm nthuav tawm (los yog hom nthuav tawm hu ua osmosis). Diffusion yog ib txoj hauv kev ntawm kev txav ntawm cov khoom hauv cov hlwb, nrog rau txoj hauv kev rau qhov tseem ceeb me me molecules hla lub cell membrane.
