Answer
(b) Nicotinamide Adenine Dinucleotide Phosphate.
NADP is NICOTINAMIDE ADENINE DINUCLEOTIDE PHOSPHATE.
All four options are near-identical, so this is a test of exact spelling. Two words are being swapped for similar ones: ADENINE (a nitrogenous base) — correct. ADENOSINE is adenine joined to a sugar, a different molecule. DINUCLEOTIDE (two nucleotides) — correct. DINUCLEOLUS is not a word at all; the NUCLEOLUS is a structure inside the nucleus.
Only option (b) has both right.
WHAT IT DOES: NADP is the hydrogen ACCEPTOR of the light reaction. The hydrogen released when water is split is picked up to form NADPH₂, which carries it into the dark reaction to reduce carbon dioxide to glucose. It is the link between the two stages of photosynthesis.
Nicotinamide Adenine Dinucleotide Phosphate.
