Question

Pick out the one which does not belong to the family.

• A. Pepsin
• B. Cellulose
• C. Ptyalin
• D. Lipase

Answer 1

The correct option is B Cellulose

Pepsin is an enzyme that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

Ptyalin: An enzyme found in the saliva of humans and herbivorous animals that helps in the predigestion of starches.

Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach.

These three are enzymes but Cellulose is a polysaccharide.

Hence, option B is correct.
