Dab tsi yog cov reactants ntawm Pyruvate Oxidation? 2 NUG, 2 CO2 , 2 Acetyl Co A.

Kuj paub, cov khoom ntawm pyruvate oxidation yog dab tsi?

Zuag qhia tag nrho, pyruvate oxidation converts pyruvate-ib peb-carbon molecule-rau hauv acetyl CoA pib ntawv, C, o, A, kawg ntawv-ib ob-carbon molecule txuas rau Coenzyme A - tsim cov ntawv NADHstart, N, A, D, H, cov ntawv kawg thiab tso tawm ib qho carbon dioxide molecule hauv cov txheej txheem.

Ib tug kuj yuav nug, dab tsi yog lub hom phiaj ntawm pyruvate oxidation? Pyruvate decarboxylation los yog pyruvate oxidation , tseem hu ua txuas cov tshuaj tiv thaiv, yog kev hloov dua siab tshiab ntawm pyruvate ua mus rau acetyl-CoA los ntawm cov enzyme complex pyruvate ua dehydrogenase complex. Lub zog-tsim ions thiab molecules xws li amino acids thiab carbohydrates nkag mus rau lub voj voog Krebs li acetyl coenzyme A thiab oxidize hauv lub voj voog.

Thiab cov lus nug yog, dab tsi yog cov reactants thiab cov khoom ntawm oxidative phosphorylation?

Zuag qhia tag nrho, cov txheej txheem tsim cov 2 pyruvate ntxiv rau 2 molecules dej, 2 ATP , 2 molecules ntawm NADH, thiab 2 hydrogen ions (H +). NADH nqa electrons mus rau oxidative phosphorylation kauj ruam ntawm cellular ua pa , uas tshwm sim hauv mitochondrion.

Muaj pes tsawg NADH tsim los ntawm pyruvate oxidation?

Txhua tig ntawm lub voj voog cov ntaub ntawv peb NADH molecules thiab ib FADH2 molecule. Cov neeg nqa khoom no yuav txuas nrog qhov kawg ntawm kev ua pa aerobic los tsim ATP molecules. Ib qho GTP lossis ATP kuj tau ua hauv txhua lub voj voog.
