Question

Arrange the following enzymes in ascending order of their optimum pH and select the correct option
(a) Salivary amylase
(b) Pepsin
(c) Pancreatic amylase

• A. (a), (b), (c)
• B. (b), (a), (c)
• C. (c), (a), (b)
• D. (c), (b), (a)

Answer 1

The correct option is B (b), (a), (c)

The optimum pH of salivary amylase is 6.8, pepsin is 1.8 and pancreatic amylase is 8. So, the ascending order of their pH will be pepsin < salivary amylase < pancreatic amylase.
Hence, the correct answer is option (2).
