Ques. 1AIPMT 2002
Hydrolytic enzymes which act at low pH are called
- proteases
- -amylases
- hydrolases
- peroxidases.
Answer
(1) proteases
Solution
As per NCERT, HCl of the gastric juice provides the acidic pH (pH 1.8) optimal for pepsin, the proteolytic enzyme of the stomach.
⇒ Pepsin (a protease) acts at low pH and converts proteins into proteoses and peptones.
∵ Salivary -amylase acts at about pH 6.8, and peroxidases are not hydrolytic enzymes.
∴ Hydrolytic enzymes which act at low pH are proteases.
