UPSC NDA-1 – 2016
– Proteins are polymers of amino acids, and digestion breaks them down into individual amino acids. (A -> 4)
– Carbohydrates (like starch, disaccharides) are broken down into monosaccharides (simple sugars like glucose, fructose, galactose). (B -> 3)
– Nucleic acids (DNA, RNA) are broken down into nucleotides, and further breakdown yields nitrogenous bases, pentose sugars, and phosphate groups. Option 1 lists nitrogenous bases and pentose sugars, which are components resulting from nucleic acid digestion. (C -> 1)
– Lipids (fats and oils) are broken down into fatty acids and glycerol. (D -> 2)
