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)
