Glycolysis, qhov twg cov piam thaj yooj yim tau tawg, tshwm sim hauv cytosol. Pyruvate, cov khoom lag luam los ntawm glycolysis, hloov mus rau acetyl CoA hauv mitochondria rau cov kauj ruam tom ntej.
Dab tsi molecule tshem tawm electrons los ntawm qabzib thaum lub sij hawm glycolysis?
Yuav kom glycolysis tshwm sim, uas yog txhawm rau txhawm rau faib cov piam thaj molecule rau hauv 2 lub molecules ntawm pyruvate, qee cov electrons yuav tsum tau muab tshem tawm ntawm cov piam thaj. Tshem tawm cov electrons los ntawm cov piam thaj ua rau cov piam thaj poob sib nrug ua ob lub molecules ntawm pyruvate.
Yuav ua li cas molecules txais electrons los ntawm qabzib?
Ntau ntau kauj ruam, txawm li cas los xij, tsim ATP hauv txoj kev tsis ncaj. Nyob rau hauv cov kauj ruam no, electrons los ntawm qabzib raug xa mus rau me me molecules hu ua electron cab kuj. Cov neeg nqa khoom siv hluav taws xob coj cov hluav taws xob mus rau ib pawg ntawm proteins nyob rau hauv daim nyias nyias ntawm lub mitochondrion, hu ua electron thauj saw.
YPuas yog piam thaj hloov mus rau acetyl-CoA hauv glycolysis?
Vim glycolysis ntawm ib lub qabzib molecule tsim ob acetyl CoA molecules , cov tshuaj tiv thaiv hauv glycolytic txoj kev thiab citric acid voj voog tsim rau CO 2molecules, 10 NADH molecules, thiab ob FADH2 molecules ib qabzib molecule (Table 16-1). … Lub zog ntxiv yog khaws cia hauv cov coenzymes txo qis, NADH thiab FADH2..
Yog acetyl-CoA siv hauvglycolysis yog dab tsi?
Ntawm cov piam thaj ntau, acetyl-CoA yog tsim los ntawm glycolysis. Pyruvate dhau oxidative decarboxylation uas nws poob nws pawg carboxyl (raws li carbon dioxide) los tsim acetyl-CoA, muab tawm 33.5 kJ / mol ntawm lub zog. … Nws yog catalyzed los ntawm pyruvate dehydrogenase complex.
