Question

The full form of NAD is
A. Adenosine diphosphate
B. Nicotinamide adenine dinucleotide
C. Nicotinamide adenine dinucleotide
D. None of the above

Answer 1

Hint: Nucleotides are the building blocks of DNAs and RNAs. They contain all the genetic information and are found in all living cells. They consist of four bases - Adenine, Thymine, Guanine and Cytosine.

Complete Answer:
Nicotinamide adenine dinucleotide (NAD) is a dinucleotide. It consists of two nucleotides, which are joined by phosphate groups. One of them has adenine base; and the other one contains nicotinamide.
The function of NAD are,
1. They play a very important role in the metabolic processes.
2. They also serve as electron carriers.

They exist in two forms, i.e. - reduced NADH & oxidised $NAD^+$.
- Nucleotides act as coenzymes, which are required to catalyse several biochemical reactions.
- Energy is stored in our body as ATP. When there is a need for the energy they get converted to ADP or AMP.
- NAD, NADP also play a very significant role in several redox reactions, since they act as electron carriers.

Thus, the correct option is C) Nicotinamide adenine dinucleotide.

Additional information: The function of nucleotides are,
- They have a role in redox reactions as they can act as an electron carrier.
- They act as coenzymes which are necessary for catalysis of many biochemical reactions by enzymes.
- They are the building block of RNA and DNA.

Note: A few ways to increase NAD Levels naturally
- Protect your body from a lot of sunlight.
- Eat the right and healthy food.
- Inculcate fasting to have a faster metabolism.
- Try your best to get enough sleep.
- Take the supplements infused with NAD.
