Question

What is the full name of NADP?
a. Nicotinamide dinucleotide phosphate
b. Nicotine adenine dinucleotide phosphate
c. Nicotinamide adenine dinucleotide phosphate
d. None of the above

Answer 1

Hint: There exist a number of non-protein molecules that assist an enzyme in bringing about a biochemical reaction like NADP, FMN, ATP, etc.

Complete answer:
‘NADP' stands for ‘Nicotinamide Adenine Dinucleotide Phosphate'.
NADP is a cofactor responsible for the transportation of electrons during metabolic processes like the Calvin cycle, synthesis of lipids, and nucleic acid.NADP consists of two nucleotide molecules bound to a phosphate group and a nicotinamide component.

Formation of NADP:
1. We all know that ADP+ is synthesized before NADPH.
2. Such a reaction usually starts with NAD+ from either the de-novo or the salvage pathway by the enzyme NAD+ kinase adding the extra phosphate group.
3. NADP+ phosphatase can convert NADPH back to NADH.

The functions of NADP are:
1. Formation of NADPH by accepting electrons and hydrogen atoms.
2. Production of energy.
3. They are required in a number of metabolic reactions like 'Pentose phosphate pathway', 'Fatty acid synthesis', 'Calvin cycle', 'synthesis of carotenoids', etc.

Note: NADPH is the reduced form of NADP. It is formed during photosynthesis by the reduction of NADP.
