Which enzyme is used to break down bacteria, yeast, and other microorganisms?

A. lyases

B. oxidoreductases

C. proteases

D. cellulases

Option C is correct.

C. proteases

Explanation:

proteases are the enzymes that used to break down bacteria, yeast, and other microorganisms.

A protease is an enzyme that performs proteolysis: protein catabolism by hydrolysis of peptide bonds. Proteases have evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms.
