Fill in the Blanks Fill in the Blanks: Krebs CycleOnline version Test your knowledge of the Krebs cycle by filling in the missing words in this interactive game! by Bio Innovators 1 FADH2 Krebs cycle electron matrix NADH transport chain Tricarboxylic acid is also known as Citric acid cycle or cycle . It occurs in the of mitochondria to provide in the form of and that are used in electron . 2 isocitrate CoA rearranged oxaloacetate, OAA addition Citrate pyruvate oxidation removal citrate Condensation Isomerization 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 ketoglutarate reduced 5-carbon decarboxylation H NAD CO2 transferring 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 CO2 succinyl CoA NADH Coenzyme A 4C molecule oxidized ketoglutarate 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 Succinate CoA GTP FAD energy ADP two hydrogen atoms FAD ATP fumarate Substrate level phosphorylation succinate GTP FADH phosphate group 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 malate Reduction Malate oxidized water molecule rearranged Fumarate oxaloacetate NADH regenerated 7 . Hydration is into by addition of one . 8 . Oxidation is . of NAD + to + H + occurs and is .
