Cov proton gradient tsim los ntawm proton Kev siv lub tshuab xa hluav taws xob xa hluav taws xob yog siv los ua ke ATP. Protons ntws los ntawm lawv cov concentration gradient mus rau hauv lub matrix los ntawm cov membrane protein ATP synthase, ua rau nws tig (zoo li lub log dej) thiab catalyze hloov dua siab tshiab ntawm ADP rau ATP.
Raws li, lub hom phiaj ntawm Proton hydrogen ion gradient yog dab tsi?
Ib qho yooj yim mechanism rau ua qhov no yog a proton twj uas txav hydrogen ions rau ib sab ntawm daim nyias nyias tsim ib proton gradient (los yog daim nyias nyias). Nyob rau hauv photosynthesis, electrons nyob rau hauv photopigments zoo siab nrog lub teeb thiab dhau los ntawm ib tug series ntawm redox tshuaj tiv thaiv hu ua ib tug electron thauj saw.
Ib sab saum toj, vim li cas proton gradient tseem ceeb hauv photosynthesis? Thoob plaws thylakoid daim nyias nyias, lub teeb induced - proton gradient yog qhov tseem ceeb rau ATP synthesis. Raws li qhov tshwm sim ntawm proton tso rau hauv thylakoid lumen, alkaline stromal pH tsim, uas yuav tsum tau ua kom tag nrho ntawm pH-nyob ntawm Calvin Benson lub voj voog enzymes.
Hais txog qhov no, txhais li cas los ntawm proton gradient?
proton gradient . Cov khoom ntawm cov saw hlau thauj electron. Ib tug ntau dua concentration ntawm protons sab nraum lub puab daim nyias nyias ntawm mitochondria tshaj li hauv daim nyias nyias yog lub zog tsav tom qab ATP synthesis.
Dab tsi yog qhov proton gradient hauv cellular respiration?
Cov electrochemical proton gradient yog qhov sib txawv hydrogen ion concentration hla ib daim nyias nyias uas ua kom muaj qhov concentration gradient thiab muaj peev xwm hluav taws xob gradient . Cellular ua pa yog nyob ntawm lub hav zoov ntawm ib qho electrochemical proton gradient nyob rau sab hauv ntawm mitochondrial membrane.

Dab tsi yog ob lub hom phiaj tseem ceeb ntawm lub voj voog citric acid?
Ob lub hom phiaj tseem ceeb ntawm lub voj voog citric acid yog: A) synthesis ntawm citrate thiab gluconeogenesis. B) degradation ntawm acetyl-CoA los tsim lub zog thiab muab cov precursors rau anabolism
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
