Question

Many enzymes are secreted in inactive form to protect

• A. Cell proteins
• B. Mitochondria
• C. Cell membrane
• D. Cell DNA

Answer 1

The correct option is A Cell proteins

The enzymes are protein in nature and they are generally produced in inactive form so to protect the intracellular damage of protein. For example, digestive enzymes are secreted in form of zymogens which remains inactive in the cells in which it is produced. The active sites are blocked by the peptide which keeps the enzyme in the inactive stage so the other proteins do not get harmed by the reaction. Cleavage of this peptide cleaves activates the enzyme.

So, the correct answer is option A.
