Question

Which of the following enzyme is not used in making detergent?

• A. Lipase
• B. Cellulase
• C. Protease
• D. Peptidase

Answer 1

Answer: (D)

Peptidase

Biological detergents are the substance which is used to remove the stain on the clothes. It cleans the dirt by breaking the fat, starch and protein in the stain. It is made by the combination of amylase, cellulase and protease. Amylase is used to break down starch based stains, cellulase to clean cotton by removing pilling fibres and protease to break down protein stains.

Peptidase enzyme helps to breaks the peptide linkage between the amino acid chain and converts the protein into the amino acid. It is not used for making the biological detergent because it can easily start the reaction with the skin and digest its proteins.

So, the correct answer is option D.
