zog uas yog tsim los ntawm kev hloov pauv ntawm cov protons lossis electrons hla lub zog-transducing membranethiab uas tuaj yeem siv rau tshuaj, osmotic, lossis kev ua haujlwm kho tshuab.
Kev ua haujlwm ntawm proton motive force yog dab tsi?
Lub zog proton-motive tsim los ntawm V-ATPases hauv organelles thiab hla plasma daim nyias nyias ntawm eukaryotic hlwb yog siv los ua lub zog tsav rau ntau cov txheej txheem thauj khoom thib ob. Lub enzyme tseem ceeb heev rau kev ua haujlwm ntawm endosomes thiab Golgi apparatus.
Dab tsi yog qhov proton motive quab yuam hauv photosynthesis?
Lub thylakoid proton motive force (pmf), lub transmembrane electrochemical gradient ntawm protons generated thaum lub teeb tshwm sim ntawm photosynthesis, yog ib qho tseem ceeb ntawm bioenergetics, coupling lub teeb-tsav electron Hloov cov tshuaj tiv thaiv rau phosphorylation ntawm ADP ntawm ATP synthase (Avenson li al., 2004; …
Proton motive force hauv mitochondria li cas?
Lub zog proton-motive tsim los ntawm qhov tso tawm ntawm cov protons los ntawm cov kab mob ua pa nyuaj yog nyob rau hauv mitochondria ntawm cov ntaub so ntswg feem ntau yog siv los hloov cov protons los ntawm ATP synthase complex, ua rau kev tsim ntawm ATP los ntawm adenosine diphosphate (ADP) thiab phosphate.
Dab tsi yog ob lub ntsiab lus ntawm proton motive force?
Lub zog protonmotive hla lub puab mitochondrial membrane (Δp) muaj ob yam: membranemuaj peev xwm (ΔΨ) thiab gradient ntawm proton concentration (ΔpH).
