Question

The enzymes which acts in low pH are called as

• A. Protease
• B. $\alpha$-amylase
• C. Hydrolases
• D. Peroxidase

Answer 1

Answer: (C)

Hydrolases

Hydrolases are the hydrolytic enzymes which are active at low pH. These enzymes are present in the lysosomes and are called as acid hydrolases. A low pH is actively maintained in the lysosomes with the help of proton pump present in the lysosomal membrane which actively pumps protons into the lysosomes.

So, the correct answer is option C.
