All of the following vitamins play a key role in the Citric acid cycle except
Correct Answer: Cobalamin
Description: VITAMINS PLAY KEY ROLES IN THE CITRIC ACID CYCLE Four of the B vitamins are essential in the citric acid cycle and hence energy-yielding metabolism: Riboflavin, in the form of flavin adenine dinucleotide (FAD), a cofactor for succinate dehydrogenase. Niacin, in the form of nicotinamide adenine dinucleotide (NAD+), the electron acceptor for isocitrate dehydrogenase, a-ketoglutarate dehydrogenase, and malate dehydrogenase. Thiamin (vitamin B1), as thiamin diphosphate, the coenzyme for decarboxylation in the a-ketoglutarate dehydrogenase reaction, and Pantothenic acid, as pa of coenzyme A, the cofactor esterified to "active" carboxylic acid residues: acetyl-CoA and succinyl-CoA.
