Conversion of malate to oxaloacetate involves what kind of reaction? dehydration reduction of a ketone to a hydroxyl group using NAD* reduction of a hydroxyl group to a carbonyl using NAD* oxidation of a carbon-carbon double bond oxidation of a hydroxyl group to a carbonyl using NAD* FADH_2 is produced in the TCA cycle as a result of what oxidation reaction? conversion of citrate to isocitrate conversion of isocitrate to a-ketoglutarate conversion of succinate to fumarate conversion of fumarate to molate conversion of malate to oxaloacetate CO_2 is generated at what two steps of the TCA cycle? oxatoacetate > citrate and citrate > isocitrate isocitrate > a-ketoglutarate and succinate > fumarate a-ketoglutarate > succinyl-CoA and succinate > fumarate succinate > fumarate and malate > oxaloacetate NADH is produced at what steps in the TCA cycle? decarboxylation of isocitrate to form a-ketoglutarate decarboxylation of a-ketoglutarate during formation of succinyl-CoA conversion of malate to oxaloacetate all of the above none of the above Fatty acid metabolism beta-oxidation of fatty adds yields what product at each step? ATP acetyl-CoA malonyl-CoA acetate CO_2 beta-oxidation of fatty acids involves what sequence of reactions? oxidation > hydration > oxidation > cleavage oxidation > oxidation > hydration > cleavage hydration > oxidation > hydration > cleavage hydration > oxidation > oxidation > cleavage cleavage > hydration > oxidation > hydration What reduced cofactors result from beta-oxidation of fatty acids?
