A. Yooj yim diffusion ua tsis yog xav tau lub zog : yooj yim diffusion xav tau ib 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; txhawb nqa nthuav tawm txav cov ntaub ntawv nrog thiab tawm tsam ib tug concentration gradient.
Hauv qhov no, puas yog diffusion xav tau lub zog?
Diffusion yog ib daim ntawv ntawm passive thauj, uas implies hais tias nws ua tsis yog xav tau kev siv ntawm zog . Diffusion yog txhais tau tias yog kev txav ntawm cov khoom los ntawm thaj chaw siab dua mus rau thaj tsam ntawm qhov qis dua.
Tsis tas li ntawd, puas yooj yim diffusion nquag lossis passive thauj? Thaum kev thauj mus los xav tau lub zog thiab ua haujlwm, passive thauj tsis. Muaj ntau ntau hom ntawm no yooj yim txav ntawm molecules. Nws yuav ua tau li yooj yim raws 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.
Ua raws li qhov no hauv kev xav, puas yooj yim diffusion yuav tsum muaj daim nyias nyias?
Diffusion hla ib lub cell daim nyias nyias yog hom passive thauj , los yog thauj thoob plaws hauv lub cell daim nyias nyias uas ua tsis yog xav tau zog. Yog li ntawd, yooj yim diffusion yog qhov tsis muaj kev pab cuam ntawm me me, hydrophobic, nonpolar molecules los ntawm qhov siab dua mus rau qis dua.
Vim li cas diffusion tsis xav tau lub zog?
Nws tshwm sim nyob rau hauv ib tug concentration gradient - molecules txav los ntawm ib thaj tsam ntawm siab mus rau qis concentration. Qhov no tsis xav tau ib qho khoom siv zog vim diffusion yog tus txheej txheem spontaneous.

Dab tsi yog qhov txawv ntawm osmosis diffusion thiab yooj yim diffusion?
Osmosis kuj tshwm sim thaum dej txav ntawm ib lub cell mus rau lwm qhov. Kev yooj yim diffusion ntawm qhov tod tes tshwm sim thaum qhov nruab nrab nyob ib puag ncig ntawm lub cell yog nyob rau hauv siab concentration ntawm ions los yog molecules tshaj qhov chaw nyob rau hauv lub cell. Cov molecules txav los ntawm ib puag ncig nruab nrab mus rau hauv lub cell vim diffusion gradient
Puas yooj yim diffusion siv cov protein raws?
Saib ze ze: Cov neeg nqa khoom yooj yim Diffusion Muaj ob hom kev sib koom ua ke ntawm cov neeg nqa khoom yooj yim: Channel proteins thauj tsuas yog dej lossis qee yam ions. Lawv ua li ntawd los ntawm kev tsim cov protein-lined passageway hla daim nyias nyias. Ntau cov dej molecules lossis ions tuaj yeem hla hauv ib cov ntaub ntawv los ntawm cov channel ntawm tus nqi nrawm heev
Puas yog yooj yim diffusion passive thauj?
Facilitated diffusion (tseem hu ua kev thauj mus los yooj yim lossis kev thauj mus los tsis tu ncua) yog cov txheej txheem ntawm kev thauj mus los tsis tu ncua (raws li tsis yog kev thauj mus los) ntawm cov molecules lossis ions hla ib daim nyias nyias ntawm cov protein tshwj xeeb transmembrane
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
