Tsis muaj oxygen , pyruvate ua ( pyruvic acid ) tsis yog metabolized los ntawm cellular respiration tab sis undergoes tus txheej txheem ntawm fermentation. Cov pyruvate ua tsis yog thauj mus rau hauv mitochondrion, tab sis tseem nyob hauv cytoplasm, qhov twg nws hloov mus rau cov khoom pov tseg uas yuav raug tshem tawm ntawm lub cell.

Yog li ntawd, pyruvate oxidation tshwm sim qhov twg?

Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis hauv cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate ua yuav tsum nkag mus rau mitochondrion, hla nws cov ntaub so ntswg thiab tuaj txog ntawm matrix.

Tsis tas li, yuav ua li cas yog tias pyruvate oxidation raug thaiv? Yog tias pyruvate oxidation raug 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.

Ib sab ntawm qhov no, yuav ua li cas rau pyruvate thaum muaj oxygen?

Txawm tias glycolysis tsis xav tau oxygen , txoj hmoo ntawm pyruvate ua molecules nyob ntawm seb muaj oxygen . Yog oxygen tsis muaj, cov pyruvate ua hloov mus rau lactate, thiab tsis muaj ATP ntxiv yog tsim los ntawm qhov kev hloov pauv no. Yog muaj oxygen , cov pyruvates raug thauj mus rau hauv mitochondrial matrix.

Puas yog kev hloov pauv ntawm pyruvate rau acetyl CoA xav tau oxygen?

Kev ua pa aerobic tshwm sim hauv mitochondria thiab xav tau lub xub ntiag ntawm oxygen . Aerobic respiration pib nrog lub Kev hloov pauv ntawm pyruvate rau hauv acetyl CoA.
