Yam yooj yim diffusion tsis tas yuav muaj zog: kev yooj yim diffusion yuav tsum muaj 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 diffusion lossis osmosis xav tau lub zog?
Ob qho tib si diffusion thiab osmosis yog cov txheej txheem thauj mus los, uas txhais tau tias lawv tsis tas yuav muaj lub zog ntxiv los tshwm sim.
Puas diffusion muaj zog?
Diffusion yog txav los ntawm qhov siab ntawm cov molecules mus rau qhov tsis tshua muaj siab ntawm cov molecules. Molecules tuaj yeem sib kis thoob plaws hauv daim nyias nyias los ntawm phospholipid bilayer lossis siv cov protein tshwj xeeb. Txhua yam kev sib kis tsis xav tau lub zog ntawm tes.
Yuav ua li cas thiaj li muaj qhov tshwm sim?
Kev piav qhia: Diffusion yog txheej txheem uas tso cai rau cov khoom txav los ntawm thaj chaw siab mus rau thaj chaw qis dua. Cov txheej txheem xav tau uas cov khoom txav. Ntev npaum li cov khoom tsis nyob ntawm qhov kub ntawm 0K (tsis muaj xoom) lawv muaj lub zog kinetic (lub zog ntawm kev txav).
Yuav siv zog li cas?
Kev piav qhia: Lub zog rau txhua qhov kev txav yog nyob rau hauv daim ntawv ntawm kinetic zog. Qhov no suav nrog kev txav mus los ntawm osmosis thiab diffusion. Lub zog Kinetic los ntawm txhua qhov chaw, vim tias txhua lub zog yeej ib yam nkaus.
