Hauv kev hloov dua siab tshiab ntawm pyruvate ua rau acetyl CoA , cwb pyruvate ua molecule poob ib qho atom nrog kev tso tawm carbon dioxide. Thaum lub sij hawm tawg ntawm pyruvate ua , electrons yog pauv mus rau NAD + los tsim NADH, uas yuav siv los ntawm tes los tsim ATP.

Ib yam li ntawd, koj tuaj yeem nug, puas yog pyruvate tib yam li acetyl CoA?

1 Teb. Pyruvate yog hloov mus rau hauv Acetyl CoA nyob rau hauv cov txheej txheem nruab nrab ua ntej Citric Acid Cycle. Ntawm no nws reacts nrog Coenzyme A. Ntawm no nws poob ob ntawm nws cov pa oxygen thiab ib qho ntawm nws yog carbons los ua carbon dioxide.

Tsis tas li ntawd, acetyl CoA tsim li cas? Acetyl - CoA yog tsim Los ntawm kev tawg ntawm ob qho tib si carbohydrates (los ntawm glycolysis) thiab lipids (los ntawm β-oxidation). Tom qab ntawd nws nkag mus rau lub voj voog citric acid hauv mitochondrion los ntawm kev sib txuas nrog oxaloacetate rau daim ntawv citrate.

Ua raws li qhov xav tau, muaj pes tsawg acetyl CoA yog tsim los ntawm pyruvate?

Ob lub molecules ntawm pyruvate hloov mus rau hauv ob molecules ntawm acetyl CoAstart ntawv, C, o, A, ntawv kawg. Ob lub carbons raug tso tawm raws li cov pa roj carbon dioxide-tawm ntawm rau lub hauv paus muaj nyob rau hauv qabzib.

Dab tsi enzyme hloov pyruvate rau acetyl CoA?

Pyruvate Dehydrogenase
