Kev yooj yim diffusion yuav tsum membrane proteins txhawm rau thauj cov roj ntsha molecules. Ib qho yooj yim diffusion yog ib qho uas tshwm sim tsis muaj kev pab los ntawm daim nyias nyias proteins. Txij li cov membrane proteins xav tau rau kev thauj mus los hauv kev yooj yim diffusion, cov nyhuv ntawm qhov kub thiab txias yog feem ntau hais ntau tshaj qhov yooj yim diffusion.
Puas txhawb kev sib kis yuav tsum muaj tus neeg nqa khoom?
Nyob rau hauv yooj yim diffusion, molecules diffuse hla cov plasma daim nyias nyias nrog kev pab los ntawm daim nyias nyias cov proteins, xws li cov channel thiab cov nqa khoom. … Txawm li cas los xij, vim lawv raug them los yog polar, lawv hla tsis tau phospholipid ib feem ntawm daim nyias nyias yam tsis muaj kev pab.
Puas pab txhawb kev nthuav dav siv cov channel lossis cov khoom thauj khoom?
Facilitated diffusion yog qhov diffusion ntawm cov kuab tshuaj los ntawm kev thauj cov proteins hauv cov plasma membrane. Channel proteins, gated channel proteins, thiab carrier proteins yog peb hom thauj cov proteins uas koom nrog hauv kev yooj yim diffusion.
Dab tsi yog qhov yooj yim diffusion xav tau?
Yooj yim diffusion tsis xav tau lub zog: yooj yim diffusion yuav tsum a qhov chaw ntawm ATP. Yooj yim diffusion tuaj yeem tsuas yog txav cov khoom nyob rau hauv cov kev taw qhia ntawm ib tug concentration gradient; yooj yim diffusion txav cov ntaub ntawv nrog thiab tawm tsam qhov concentration gradient.
Puas muaj cov protein ntau hauv kev yooj yim diffusion xav tau lub zog?
Txawm li cas los xij, tus neeg nqa khoomCov proteins kuj tseem siv tau rau kev yooj yim diffusion, ib daim ntawv ntawm kev thauj mus los passive. … Qee cov neeg nqa khoom proteins xav tsis muaj lub zogtab sis qhov sib txawv ntawm qhov chaw uas lawv cov substrate "xav tau" dhau mus, ua rau lawv ib qho kev thauj mus los.
