- A portion of the citric acid cycle is shown below. What are the identities of A and B? citrate → A→isocitrate → B A = cis-aconitate; B = a-ketoglutarate A = malate; B = fumarate A = cis-aconitate; B = oxaloacetate A = a-ketoglutarate; B = succinate A = succinate; B = a-ketoglutaratearrow_forwardMost fatty acids have an even number of carbons and, therefore, are completely metabolized to acetyl-CoA. A fatty acid with an odd number of carbons is metabolized to acetyl-CoA and one equivalent of propionyl-CoA. The following two reactions convert propionyl-CoA into succinyl-CoA, a citric acid cycle intermediate, so it can be further metabolized. Each of the reactions requires a coenzyme. Identify the coenzyme for each step. From what vitamins are the coenzymes derived?arrow_forward
