Citric Acid c. Isocitrate d. Alpha-ketoglutarate e. Succinyl-CoA f .Succinate g. Fumarate h. MalateA fatty acid (a long straight-chain carboxylic acid with an even number of carbons) is metabolized to acetyl- CoA, which can then enter the citric acid cycle to be further metabolized (Section 24.9). A fatty acid with anodd number of carbons is metabolized to acetyl-CoA and one equivalent of propionyl-CoA. Propionyl-CoA cannot enter the citric acid cycle. Two coenzyme-requiring enzymes are needed to convert it to succinyl-CoA, acompound that can enter the citric acid cycle. Write the two enzyme-catalyzed reactions and include the names of the required coenzymes.49. Which of these is NOT true of the citric acid cycle? Group of answer choices The citric acid cycle uses both NAD+ and FADH as electron carriers. The citric acid cycle produces ATP via oxidative phosphorylation. The citric acid cycle produces two ATP per glucose molecule. The citric acid cycle occurs in the mitochondria.
