Hauv prokaryotes, nws tshwm sim hauv cytoplasm. Zuag qhia tag nrho, pyruvate oxidation hloov pyruvate ua -a peb-carbon molecule-rau hauv acetyl CoA pib ntawv, C, o, A, kawg ntawv-ib ob-carbon molecule txuas rau Coenzyme A-ua ib qho NADH pib ntawv, N, A, D, H, ntawv kawg thiab tso ib qho carbon dioxide molecule nyob rau hauv tus txheej txheem.

Hauv qhov no, dab tsi yog cov reactants ntawm pyruvate oxidation?

2 NADH , 2 CO2, 2 Acetyl Co A.

Ib sab saum toj, puas pyruvate oxidation xav tau oxygen? Glycolysis tuaj yeem tshwm sim yam tsis muaj oxygen nyob rau hauv ib tug txheej txheem hu ua fermentation. Lwm peb theem ntawm cellular respiration- pyruvate oxidation oxidative phosphorylation thiab citric acid voj voog, xav tau oxygen thiaj li tshwm sim.

Tsis tas li ntawd, qhov twg oxidation ntawm pyruvate tshwm sim?

Hauv eukaryotic hlwb, lub pyruvate ua Cov molecules uas tsim thaum kawg ntawm glycolysis raug thauj mus rau hauv mitochondria, uas yog qhov chaw ntawm cellular respiration. Nyob ntawd, pyruvate ua yuav hloov mus rau hauv ib pawg acetyl uas yuav tau khaws thiab ua haujlwm los ntawm cov cab kuj hu ua coenzyme A (CoA).

Yuav ua li cas tshwm sim thaum pyruvate oxidation raug thaiv?

Yog pyruvate oxidation yog thaiv , dab tsi yuav tshwm sim mus rau theem ntawm oxaloacetate thiab citric acid nyob rau hauv lub voj voog citric acid qhia hauv daim duab hauv qab no? Oxaloacetate yuav sib sau thiab citric acid yuav txo qis. Ob qho tib si oxaloacetate thiab citric acid yuav khaws cia. Ob qho tib si oxaloacetate thiab citric acid yuav txo qis.
