Question

During glycolysis, two hydrogen atoms are picked up by the coenzyme nicotinamide adenine dinucleotide (NAD). What B vitamin is required for synthesis of this coenzyme?
a. niacin
b. pantothenic acid
c. riboflavin
d. biotin

Answer 1

Answer:

Niacin (Ans. A)

Explanation:

Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.

Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.

These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.
