3. nucleic acid
4. vitamin.

Answer

(1) nucleotide

Solution

As per NCERT, a nitrogenous base attached to a sugar is a nucleoside (e.g. adenosine); when a phosphate group is also esterified to the sugar, it is a nucleotide.

⇒ ATP = adenine + ribose + three phosphate groups, i.e. adenosine triphosphate.

∴ ATP is a nucleotide.
