2: Kev hloov pauv hloov: Pyruvic Acid yog shuttle mus rau mitochondria, qhov twg nws yog xa mus rau ib lub molecule hu ua Acetyl CoA ntxiv kev tawg . 3: Lub Krebs Cycle, lossis Citric Acid Lub voj voog: tshwm sim Nyob rau hauv lub mitochondrial matrix, lub kua-y ib feem ntawm lub mitochondria.

Kuj nug, pyruvic acid nyob qhov twg?

Pyruvic acid los yog pyruvate ua yog ib qho tseem ceeb nruab nrab ntawm glycolytic thiab pyruvate ua dehydrogenase txoj hauv kev, uas koom nrog hauv kev tsim hluav taws xob lom. Pyruvate yog dav pom nyob rau hauv cov tsiaj muaj sia. Nws tsis yog ib qho tseem ceeb ntawm cov as-ham vim nws tuaj yeem ua ke hauv cov hlwb ntawm lub cev.

Tsis tas li ntawd, kev puas tsuaj ntawm pyruvic acid cuam tshuam li cas rau lub voj voog citric acid? Pyruvic acid yog thawj zaug dehydrogenated rau acetyl-CoA nyob rau hauv mitochondrion poob ib carbon li CO2. Qhov no yog qhov kev txiav txim ntawm pyruvate dehydrogenase. Tom qab ntawd Acetyl-CoA txuas ntxiv mus rau hauv citric acid voj voog (Daim duab 1.3. Ib qho thib ob carbon yog tom qab ntawd poob li CO2 ua 4-carbon qauv succinyl-CoA.

Ntawm no, ob yam dab tsi tuaj yeem tshwm sim rau pyruvic acid?

Pyruvic acid muab lub zog rau cov hlwb nyob hauv lub voj voog citric acid (tseem hu ua Krebs cycle) thaum oxygen tam sim no ( aerobic ua pa ); Nws ferments los tsim lactic acid thaum oxygen tsis muaj (fermentation). Pyruvate yog cov zis ntawm lub anaerobic Cov metabolism hauv qabzib hu ua glycolysis.

Yuav ua li cas rau pyruvic acid tom qab glycolysis?

Tom qab glycolysis , pyruvate ua yog hloov mus rau hauv acetyl CoA thiaj li nkag mus rau citric kua qaub lub voj voog.
