Teb tiav: Kev Xaiv A: Cov tshuaj tiv thaiv oxidation lossis dehydrogenation tshwm sim four times hauv Krebs cycle: Alpha-ketoglutarate rau isocitrate ([NADH] yog tsim).
Muaj pes tsawg zaus dehydrogenation tshwm sim hauv Krebs lub voj voog?
Hauv Kreb lub voj voog cov tshuaj tiv thaiv oxidation lossis dehydrogenation tshwm sim 4 zaug raws li hauv qab no: Isocitrate rau alpha-ketoglutarate (NADH yog tsim)
Ntau npaum li cas Decarboxylations tshwm sim hauv lub voj voog Krebs?
- Qhov thib ob oxidative decarboxylation tshwm sim nyob rau theem thib tsib ntawm Krebs lub voj voog uas lub molecule ntawm coenzyme-A reacts nrog α-ketoglutarate los tsim 4-carbon compound succinyl-coenzyme A thiab tso pa carbon dioxide thiab a khub ntawm hydrogen atoms. Yog li, cov lus teb yog, " Two".
Ntau npaum li cas ATPS tau tsim hauv Krebs?
Lub voj voog Krebs ua rau CO2 uas koj ua pa tawm. Cov theem no ua rau feem ntau ntawm lub zog (34 ATP molecules, piv rau tsuas yog 2 ATP rau glycolysis thiab 2 ATP rau Krebs voj voog). Cov saw hlau thauj electron tshwm sim hauv mitochondria. Cov theem no hloov NADH rau ATP.
Qhov twg ntawm cov kauj ruam hauv qab no ntawm Krebs lub voj voog cuam tshuam nrog dehydrogenation?
Nyob rau hauv Kreb lub voj voog cov tshuaj tiv thaiv oxidation lossis dehydrogenation tshwm sim 4 zaug raws li hauv qab no: Isocitrate rau alpha-ketoglutarate (NADH yog tsim) alpha-ketoglutarate rau succinyl co-A (NADH yog tsim) Succinate rau Fumarate (FADH2 yog tsim)

Lub sijhawm calvin lub voj voog twg ntawm cov hauv qab no tshwm sim?
Qhov twg hauv qab no tshwm sim thaum Calvin lub voj voog ntawm photosynthesis? Cov pa roj carbon dioxide hloov mus rau cov tshuaj uas tuaj yeem siv los ua suab thaj. Koj nyuam qhuav kawm 50 nqe lus! Dab tsi tshwm sim thaum lub caij Calvin?
Thaum twg lub voj voog krebs tshwm sim?
Lub Krebs lub voj voog nws tus kheej tiag tiag pib thaum acetyl-CoA ua ke nrog plaub-carbon molecule hu ua OAA (oxaloacetate) (saib daim duab saum toj no). Qhov no tsim citric acid, uas muaj rau carbonatos. Qhov no yog vim li cas lub voj voog Krebs tseem hu ua lub voj voog citric acid.
Puas yog lub voj voog krebs tshwm sim?
Lub voj voog Krebs nyob qhov twg? Lub voj voog TCA tau pom thawj zaug hauv cov leeg nqaij ntawm tus nquab. Nws tshwm sim nyob rau hauv tag nrho cov eukaryotic thiab prokaryotic hlwb. Hauv eukaryotes, nws tshwm sim hauv matrix ntawm mitochondrion.
Ntau npaum li cas atp raug tsim nyob rau hauv tca voj voog?
2 ATPs yog tsim nyob rau hauv TCA voj voog ib piam thaj molecule (2 acetyl CoA). Ntau npaum li cas ATP raug tsim nyob rau hauv lub voj voog citric acid? Lub voj voog citric acid yog cov tshuaj tiv thaiv uas ua rau ob lub pa roj carbon dioxide molecules, ib GTP / ATP, thiab txo cov ntawv ntawm NADH thiab FADH2.
Lub voj voog twg yog lub voj voog sib luag?
Ib lub voj voog sib luag suav nrog ceg kom tam sim no faib thiab tsuas yog ib feem ntawm nws ntws los ntawm txhua ceg. Qhov hluav taws xob, lossis qhov sib txawv ntawm qhov sib txawv, hla txhua ceg ntawm lub voj voog sib luag yog tib yam, tab sis cov dej ntws tuaj yeem sib txawv.
