A 6- carbon qab zib molecule muab faib ua ob 3- carbon molecules hu ua pyruvates. Pyruvate yog xav tau nyob rau hauv thiaj li yuav tsim acetyl CoA . Qhov no yog ib kauj ruam luv luv ntawm glycolysis thiab citric acid voj voog.

Cov lus nug tseem yog, yuav ua li cas rau cov pa roj carbon monoxide hauv acetyl CoA molecules?

Acetyl CoA txuas glycolysis thiab pyruvate ua oxidation nrog citric acid voj voog. Acetyl CoA thiab Citric Acid Cycle: Rau txhua tus molecule ntawm acetyl CoA uas nkag mus rau lub voj voog citric acid, ob carbon cov pa roj carbon dioxide molecules raug tso tawm, tshem tawm carbons los ntawm acetyl pab pawg

Tsis tas li ntawd, pes tsawg ATP yog tsim los ntawm acetyl CoA? Txhua acetyl-CoA yields 3 NADH + 1 FADH2 + 1 GTP (= ATP) thaum lub sij hawm Krebs. Xav txog qhov nruab nrab ntau lawm ntawm 3 ATP / NADH thiab 2 ATP /FADH2 siv txoj hlua ua pa, koj muaj 131 ATP molecules.

Ua li no, muaj pes tsawg carbons acetyl CoA muaj?

2 carbons

Acetyl CoA puas tuaj yeem hloov mus rau cov piam thaj?

Fatty acids thiab ketogenic amino acids tsis tuaj yeem siv los ua ke qabzib . Cov kev hloov pauv hloov yog ib qho kev tawm tsam ib leeg, txhais tau tias acetyl - CoA ua tsis tau hloov dua siab tshiab rov qab mus rau pyruvate. Yog li ntawd, fatty acids tau 'tsis siv los ua ke qabzib , vim beta-oxidation tsim acetyl - CoA.
