Question

What is common among amylase, renin and trypsin?

• A. These are all proteins
• B. These are proteolytic enzymes
• C. These are produced in stomach
• D. These act at a pH lower than 7

Answer 1

The correct option is A These are all proteins

Amylase is a protein-based enzyme that is secreted by the salivary glands of mouth and is involved in the breakdown of starch. It functions in a neutral pH (pH 7). Renin is also a protein enzyme secreted in the stomach and involved in the coagulation of milk. It functions in a acidic pH. Trypsin is also a protein enzyme that is produced in the small intestine and is a proteolytic enzyme. It also functions in acidic pH. So, the correct answer is 'These are all proteins'.
