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 yuav tsum nkag mus rau hauv mitochondrion , hla nws daim nyias nyias thiab tuaj txog ntawm matrix.

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

2 NADH , 2 CO2, 2 Acetyl Co A.

Tsis tas li ntawd, pyruvate nkag mus rau mitochondria li cas? Kev thauj mus los ntawm pyruvate ua rau hauv mitochondria yog los ntawm kev thauj cov protein pyruvate ua translocase. Pyruvate translocase thauj pyruvate ua nyob rau hauv ib tug symport zam nrog ib tug proton, thiab li no yog active, siv zog. Thaum nkag mus rau lub mitochondria , cov pyruvate ua yog decarboxylated, tsim acetyl-CoA.

Qhov thib ob, qhov twg glycolysis tshwm sim hauv lub cell?

Glycolysis siv qhov chaw hauv cytoplasm. Nyob rau hauv lub mitochondrion, lub citric acid voj voog tshwm sim nyob rau hauv lub mitochondrial matrix, thiab oxidative metabolism tshwm sim nyob rau hauv lub puab folded mitochondrial membranes (cristae).

Lub luag haujlwm tseem ceeb ntawm pyruvate yog dab tsi?

Pyruvate yog ib tseem ceeb chemical compound hauv biochemistry. Nws yog qhov tsim tawm ntawm cov metabolism hauv qabzib hu ua glycolysis. Ib qho molecule ntawm qabzib tawg mus rau hauv ob molecules ntawm pyruvate ua , uas yog siv los muab lub zog ntxiv, hauv ib qho ntawm ob txoj kev.
