Thaum lub sijhawm them nyiaj ntawm glycolysis, plaub pawg phosphate raug xa mus rau ADP los ntawm substrate-theem phosphorylation los ua plaub ATP, thiab ob NAD yog tsim thaum lub pyruvate oxidized.
Tom qab ntawd, NADH puas tsim nyob rau hauv pyruvate oxidation?
Pyruvate oxidation kauj ruam Ib pawg carboxyl raug tshem tawm ntawm pyruvate ua thiab tso tawm raws li carbon dioxide. Ob-carbon molecule los ntawm thawj kauj ruam yog oxidized , thiab NAD + lees txais cov electrons los tsim NADH . Cov oxidized Ob-carbon molecule, ib pawg acetyl, txuas rau Coenzyme A los tsim acetyl CoA.
Ib sab saum toj no, cov khoom ntawm pyruvate oxidation yog dab tsi? Pyruvate oxidation tsim acetyl Coenzyme A, NADH thiab carbon dioxide.
Hauv qhov no, pes tsawg NADH raug tsim tawm hauv glycolysis?
ob NAD
Muaj pes tsawg NADH thiab fadh2 raug tsim hauv glycolysis?
Txij li thaum glycolysis ntawm ib qho qabzib molecule tsim ob acetyl CoA molecules, cov tshuaj tiv thaiv nyob rau hauv glycolytic txoj kev thiab citric acid voj voog tsim tawm six CO2 molecules, 10 NADH molecules, thiab ob FADH 2 molecules rau cov piam thaj molecule (Table 16-1).

Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?
Muaj pes tsawg ATP raug tsim nyob rau hauv acetyl CoA tsim?
Txhua acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (= ATP) thaum lub sij hawm Krebs. Xav txog qhov nruab nrab ntawm 3 ATP / NADH thiab 2 ATP / FADH2 siv cov saw ua pa, koj muaj 131 ATP molecules
Muaj pes tsawg NADH tsim los ntawm pyruvate oxidation?
Kev ua tau zoo ntawm ATP ntau lawm Kauj Ruam coenzyme yield ATP tawm los Glycolysis them nyiaj theem 2 NADH 3 lossis 5 Oxidative decarboxylation ntawm pyruvate 2 NADH 5 Krebs cycle 2 6 NADH 15
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
