theem kawg ntawm oxidative phosphorylation yog ua los ntawm ATP synthase, ATP-synthesizing sib dhos uas tau tsav los ntawm ntws ntawm protons rov qab rau hauv mitochondrial matrix. Cheebtsam ntawm no zoo kawg nkaus enzyme tig raws li ib feem ntawm nws catalytic mechanism.
ATP synthase powered li cas?
The ATP synthase (los yog F1F0 ATPase thiab tseem hu ua complex V) siv lub zog pub dawb ntawm ib qho electrochemical gradient ntawm protons (los yog sodium ions) tsim los ntawm cov kab mob ua pa los ua ke ATP.
Dab tsi ua rau ATP synthesis thaum oxidative phosphorylation?
Txheej txheem cej luam ntawm oxidative phosphorylation. Cov saw hlau thauj khoom siv hluav taws xob tsim cov proton gradient hla lub puab mitochondrial membrane, uas tsav cov synthesis ntawm ATP ntawm chemiosmosis.
Dab tsi ua rau ATP synthase rau ATP?
ATP synthase siv cov protons ntws mus rau hauv matrix los khi ADP thiab Pi thiab tso ATP. F1-ATPase yog lub npe los ntawm qhov rov qab cov tshuaj tiv thaiv nws catalyzes thaum nws cais tawm ntawm mitochondria thiab yog li uncoupled los ntawm proton gradient.
YPuas ATP synthase powered by ATP?
ATP Synthase Txhais
ATP synthase cov ntawv ATP los ntawm adenosine diphosphate (ADP) thiab inorganic phosphate (P i) los ntawm oxidative phosphorylation, uas yog txheej txheem hauv uas enzymes oxidize as-ham los tsim ATP. ATP synthase muaj nyob rau hauv tag nrho cov lifeforms thiab powers tag nrho cov cellular kev ua ub no
Pom zoo:
Rau qhov kev ua ub no yog cov txheej txheem oxidative feem ntau siv?
Cov kab mob oxidative, thawj qhov chaw ntawm ATP thaum so thiab thaum lub sijhawm ua haujlwm qis, siv feem ntau carbohydrates thiab rog li substratesUa raws li qhov pib ntawm kev ua, raws li kev siv ntawm Kev tawm dag zog nce ntxiv, muaj kev hloov pauv hauv substrate nyiam los ntawm cov rog mus rau carbohydrates .
Thaum symplastic lub intercellular txav ntawm dej yog los ntawm?
Thaum lub sijhawm txav mus los, cov dej mus los ntawm cov hlwb - lawv cov cytoplasm; intercellular zog yog los ntawm the plasmodesmata. Symplastic txav tuaj yeem tau txais kev pab los ntawm cytoplasmic streaming . Yuav ua li cas yog dej symplastic?
Los ntawm oxidative kev nyuaj siab?
Thaum oxidative kev nyuaj siab, cov dawb radicals ntau dhau tuaj yeem ua rau cov qauv hauv lub hlwb puas tsuaj thiab tseem ua rau cell tuag, uas yuav ua rau muaj kev pheej hmoo ntawm Parkinson's disease. Oxidative stress kuj hloov cov proteins tseem ceeb, xws li amyloid-beta peptides .
Phosphorylation tau tshawb pom li cas?
Thawj phosphorylase enzyme tau tshawb pom los ntawm Carl thiab Gerty Cori hauv lig 1930s … phosphorylase los ntawm kev pab hloov pauv ntawm pawg γ-phosphoryl ntawm ATP mus rau serine residue ntawm phosphorylase b . phosphorylation nyob qhov twg?
Thaum dazzled los ntawm lub teeb ntawm lub tsheb yuav los?
Kev cog qoob loo: Yog tias dazzled los ntawm lub teeb ntawm lub tsheb yuav los, tsis txhob ntsia ncaj qha rau ntawm lub teeb yuav losHloov maj mam mus rau ntawm lub verge kom txog thaum lub tsheb dhau mus thiab / lossis qeeb. thiab nres yog tias tsim nyog.
