Concept explainers
(a)
Interpretation:
Riboflavin is needed or not for the proper functioning of the CAC has to be determined.
Concept introduction:
Citric acid cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and CoA-SH. Carbon dioxide produced is exhaled out in the breathing process. The reduced form of nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FADH2) is also produced. An overview of the citric acid cycle is:
The B-vitamins consist of a group of vitamins that are water soluble and acts as precursors for enzyme cofactors.
(b)
