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).
Pom zoo:
Vim li cas motive txhais tau tias?
Kev xav txhais tau tias a vim li cas ua ib yam. Ib qho piv txwv ntawm kev mob siab rau yog vim li cas rau kev ua txhaum cai. Qee qhov tsav sab hauv, impulse, kev xav, thiab lwm yam uas ua rau tus neeg ua ib yam dab tsi los yog ua raws li qee txoj kev;
Thaum lub sijhawm ua pa ntawm tes uas ntawm cov hauv qab no tso tawm los ntawm cov khoom lag luam?
Thaum lub sijhawm ua pa aerobic cellular, qabzib reacts nrog oxygen, tsim ATP uas tuaj yeem siv los ntawm tes. carbon dioxide thiab dej yog tsim los ntawm cov khoom lag luam. Hauv kev ua pa ntawm tes, qabzib thiab oxygen hnov qab tsim ATP.
Dab tsi yog qhov ceev ntawm cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece?
1. Kev nrawm . Kev txiav ceev (v) ntawm ib lub cuab yeej yog qhov ceev uas cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece. Nyob rau hauv ib lub tshuab dhos, nws yog lub peripheral ceev ntawm kev ua hauj lwm yav dhau los cov cuab yeej txiav qhia nyob rau hauv meters ib feeb.
Lub sijhawm twg ntawm tus mob syphilis yog tus cwj pwm los ntawm qhov pom ntawm chancre?
Primary Stage Cov tsos mob ntawm ib leeg chancre qhia txog thawj (thawj) theem ntawm cov tsos mob syphilis, tab sis tej zaum yuav muaj ntau qhov mob. Lub chancre feem ntau yog (tab sis tsis tas li) khov kho, puag ncig, thiab tsis mob. Nws tshwm ntawm qhov chaw uas tus mob syphilis nkag mus rau hauv lub cev.
Los ntawm qhov kev txiav txim ntawm enzymes tus nqi ntawm cov tshuaj tiv thaiv biochemical?
Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj zog rau cov tshuaj tiv thaiv. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes nrawm cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
