An unknown enzyme 'E' completely digests a biological polymer into its constituent monomers. The covalent bonds being broken by this enzyme were originally formed by a dehydration reaction between the carboxyl ( -COOH ) group of one monomer and the amino ( -NH₂ ) group of the adjacent monomer. Identify the class of enzyme 'E' and the specific name of the bond it hydrolyses.

Options

  1. AAmylase and Glycosidic bond
  2. BLipase and Ester bond
  3. CProtease and Peptide bond
  4. DNuclease and Phosphodiester bond

Correct answer

C. Protease and Peptide bond

Step-by-step solution

The bond formed by a dehydration reaction (removal of a water molecule) between the carboxyl ( -COOH ) group of one monomer and the amino ( -NH₂ ) group of the adjacent monomer is a peptide bond, which links amino acids. Proteins are polymers of amino acids linked by these peptide bonds. The class of enzymes that hydrolyse peptide bonds to digest proteins into amino acids is protease. Amylases break glycosidic bonds in carbohydrates, lipases break ester bonds in lipids, and nucleases break phosphodiester bonds in n
