Class 11 NEET Biology Biomolecules Questions

The correct matchings are :
(A) Protein - This is a polymer made up of amino acids linked by peptide bonds. So, (A) matches with (IV) Peptide bonds.
(B) Unsaturated fatty acid - These have one or more C=C double bonds in their hydrocarbon chain. So, (B) matches with (I) C=C double bonds.
(C) Nucleic acid - These are polymers made up of nucleotides linked by phosphodiester bonds. So, (C) matches with (II) Phosphodiester bond.
(D) Polysaccharide - These are polymers made up of monosaccharides linked by glycosidic bonds. So, (D) matches with (III) Glycosidic bonds.
So, the correct answer is Option C : (A)-(IV), (B)-(I), (C)-(II), (D)-(III).
