Question

NADP is
A)An enzyme
B)An ion carrier
C)A coenzyme
D)A part of T-RNA

Answer 1

It is a non-proteinous organic compound that catalyzes the reaction by binding with an enzyme. They are broadly called cofactors but chemically different. It's not able to function alone but can be reused many times whenever paired with an enzyme

Complete answer
-By the light reactions of photosynthesis, NADP is produced which is a reducing agent and in the Calvin cycle, it is consumed. It is also used in many other anabolic reactions occurring in both plants and animals.
-A coenzyme that performs as a universal electron carrier that accepts electrons in the hydrogen atom to form NADPH or nicotinamide adenine dinucleotide phosphate is known as ${ NADP }^{ + }$.
-${ NADP }^{ + }$ is produced during the anabolic reactions or that reactions which build a large molecule from small molecules

Additional information
-An enzyme - is a protein and a biological catalyst. It helps in increasing the rate of a specific chemical reaction in a cell. It is used over and over as it is not destroyed during the reaction.
-An ion carrier- it helps in reversibly binding the ions. It facilitates the transporting of the ions across the cell membrane. Hence it is a lipid soluble entity.
-Across the hydrophobic membranes like liquid polymeric membranes or lipid bilayer which are generally found in the living cells or synthetic vesicles, an ion transport catalysis takes place by an ion carrier.
-A part of T-RNA - the anticodon Delhi Terminal 3 hydroxyl group are the two most important parts of T-RNA. Ester linkage with an amino acid is formed by them.

So, the correct answer is,” a coenzyme”.

Note:
-A coenzymes that are similar in functions to NAD in many oxidation-reduction reactions is nicotinamide adenine dinucleotide phosphate is called a coenzyme NADP, ${ C }_{ 21 }{ H }_{ 28 }{ N }_{ 7 }{ O }_{ 17 }{ P }_{ 3 }$.
-It also functions as a universal electron carrier that has electrons in hydrogen atoms for the formation of NADPH, or nicotinamide adenine dinucleotide phosphate.
