67.NAD is: A. Nicotinamide adenosine disphospahte B. Nicotine adenosine phosphate C. Nicotinamide Adenine dinucleotide D. None of the above
Option C The full form of NAD is Nicotinamide Adenine Dinucleotide. It is defined as a cofactor in the metabolism process. It is found in all the living cells and it is named so because it contains two nucleotides attached with their phosphate groups. One among the two has an adenine nucleobase and the other is nicotinamide. NAD is known to exist in two forms in cells as an oxidized form which is abbreviated as NAD+ and a reduced form which is abbreviated as NADH, Here H stands for hydrogen. The main function of NAD is known to be the function of electron transfer or in metabolism, it is seen to carry out most of the redox reactions carrying the electrons from one reaction to the other.
