Acetyl - CoA yog ib qho tseem ceeb biochemical molecule nyob rau hauv cellular ua pa . Nws yog ua nyob rau hauv lub thib ob kauj ruam ntawm aerobic ua pa Tom qab glycolysis thiab nqa cov pa roj carbon atoms acetyl pab pawg rau TCA lub voj voog kom oxidized rau kev tsim hluav taws xob.
Hais txog qhov no, acetyl CoA siv rau dab tsi?
Acetyl coenzyme A, los yog zoo dua lub npe acetyl - CoA , yog ib qho tseem ceeb molecule siv hauv cov txheej txheem metabolic. Nws yog qhov tseem ceeb siv los ntawm lub cev rau lub zog tsim los ntawm lub voj voog citric acid, lossis Krebs cycle.
Kuj Paub, vim li cas pyruvate yuav tsum tau hloov mus rau acetyl CoA? Hauv 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 rau NAD + los tsim NADH, uas yuav siv los ntawm tes los tsim ATP.
Tsis tas li ntawd, ua li cas rau acetyl coenzyme A thaum ua pa?
Acetyl Coenzyme Kev Tsim Hauv cov txheej txheem, txhua pyruvic acid molecule poob ib carbon atom, uas ua ke nrog muaj oxygen los tsim carbon dioxide, uas yog tso tawm los ntawm exhaling. Nicotinamide adenine dinucleotide, los yog NAD, kuj nqa tawm hydrogen hauv cov txheej txheem ntawm oxidation, ua NADH.
Acetyl CoA ua 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.
Pom zoo:
Dab tsi carbons los ntawm qabzib nyob hauv acetyl CoA?
Ib qho 6-carbon qabzib molecule raug faib ua ob 3-carbon molecules hu ua pyruvates. Pyruvate yog xav tau los tsim acetyl CoA. Qhov no yog ib kauj ruam luv luv ntawm glycolysis thiab citric acid voj voog
Cov mis ntawm acetyl chloride yog dab tsi?
CH3 COJ Yog li ntawd, qhov kev txiav txim ntawm acetyl chloride yog dab tsi? Acetyl chloride yog ib qho tseem ceeb acetylating tus neeg sawv cev nrog lub peev xwm acylation muaj zog dua acetic anhydride . Nws yog dav siv hauv organic synthesis thiab dyes.
Lub luag haujlwm ntawm acetyl CoA yog dab tsi?
Acetyl-CoA (acetyl coenzyme A) yog ib qho molecule uas koom nrog ntau yam tshuaj lom neeg hauv cov protein, carbohydrate thiab lipid metabolism. Nws lub luag haujlwm tseem ceeb yog xa cov acetyl pawg mus rau lub voj voog citric acid (Krebs cycle) kom oxidized rau lub zog tsim khoom
Yuav ua li cas pyruvate tsim acetyl CoA?
Hauv kev hloov pauv ntawm pyruvate rau acetyl CoA, txhua tus pyruvate molecule poob ib qho carbon atom nrog kev tso tawm carbon dioxide. Thaum lub sij hawm tawg ntawm pyruvate, electrons raug xa mus rau NAD + los tsim NADH, uas yuav siv los ntawm tes los tsim ATP
Lub zog pauv li cas hauv photosynthesis thiab cellular respiration?
Photosynthesis yog cov txheej txheem ntawm kev hloov lub teeb lub zog rau hauv lub zog tshuaj hauv daim ntawv ntawm cov piam thaj, hauv cov qauv me me hu ua chloroplasts. Hauv kev ua pa ntawm tes, lub zog khaws cia hauv cov ntawv cog lus ntawm cov piam thaj molecule tau tawg thiab hloov mus rau lwm hom zog, ATP
