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.

Dab tsi txaus ntshai zoo kawg li nws yog qhov peb yuav tsum tau khawb trenches thiab sim cov roj npog qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob hauv lub tebchaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi?
Qhov txaus ntshai npaum li cas, zoo heev, zoo kawg yog tias peb yuav tsum tau khawb trenches thiab sim roj-qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob rau hauv ib lub teb chaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi. Nws zoo nkaus li tseem tsis yooj yim dua tias kev sib cav uas twb tau hais tseg hauv txoj cai yuav tsum yog kev ua tsov rog
Yuav ua li cas tshwm sim thaum lub concentration ntawm qabzib nyob rau hauv cov dej sab nraum lub cell yog siab tshaj qhov concentration nyob rau hauv?
Yog hais tias qhov concentration ntawm qabzib nyob rau hauv dej sab nraud ntawm lub cell yog siab tshaj qhov concentration hauv, dej yuav nyiam tawm hauv lub cell los ntawm osmosis. c. Cov piam thaj yuav zoo li nkag mus rau hauv lub cell los ntawm osmosis
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
Acetyl CoA ua dab tsi hauv cellular respiration?
Acetyl-CoA yog ib qho tseem ceeb biochemical molecule hauv cellular respiration. Nws yog tsim nyob rau hauv lub thib ob kauj ruam ntawm aerobic respiration tom qab glycolysis thiab nqa cov pa roj carbon atoms ntawm pab pawg neeg acetyl mus rau lub TCA voj voog yuav oxidized rau lub zog tsim
Muaj pes tsawg carbons nyob rau hauv fumarate?
Lub citric acid voj voog nruab nrab, fumarate, muaj plaub atoms ntawm carbon. Raws li cov qauv ntawm kev siv, ib qho molecule ntawm qabzib, cov khoom pib rau glycolysis, muaj rau atoms ntawm carbon
