It occurs in the of mitochondria to provide in the form of and that are used in electron . 2 Citrate isocitrate pyruvate oxidation oxaloacetate, OAA CoA removal Isomerization rearranged citrate addition Condensation 1 . Acetyl - CoA from removes group . The remaining acetyl combines with to form . 2 . is then to its isomer , by the of one water molecule and of one water molecule . 3 CO2 H decarboxylation ketoglutarate transferring NAD reduced 5-carbon 3 . Oxidative decarboxylation Isocitrate loses a molecule of , forming a molecule ( ) . The remaining 5 - carbon is oxidized into ? - , by their electrons and + to NAD + . + is to NADH + H + . 4 oxidized Coenzyme A CO2 ketoglutarate NADH 4C molecule succinyl CoA 4 . Oxidative decarboxylation ? - lose a molecule of forming a 4C molecule . The remaining is before combining with , to form . NAD + is reduced to + H + . 5 fumarate GTP succinate ATP Substrate level phosphate group CoA GTP FAD FAD FADH Succinate phosphorylation energy two hydrogen atoms ADP 5 . phosphorylation Succinyl - CoA loses and converted to . The released is used in the of GDP to form . then transfer its to to form . 6 . Oxidation is oxidized to , by transferring to . is reduced to . 6 NADH malate oxaloacetate water molecule oxidized rearranged Malate Reduction Fumarate regenerated 7 . Hydration is into by addition of one . 8 . Oxidation is . of NAD + to + H + occurs and is .
