Question:
The optimum pH at which the enzymes pepsin and trypsin of the human alimentary canal works are
The optimum pH at which the enzymes pepsin and trypsin of the human alimentary canal works are
Options:
- pH 2.0 and 7.9, respectively
- pH 4.5 and 3.5, respectively
- pH 9.5 and 4.5, respectively
- pH 7.0 and 8.0, respectively
- pH 2.0 and 7.9, respectively
- pH 4.5 and 3.5, respectively
- pH 9.5 and 4.5, respectively
- pH 7.0 and 8.0, respectively
Correct Answer: pH 2.0 and 7.9, respectively
Explanation:
Pepsin functions in the acidic environment of the stomach (optimum pH of 1.5-2.0). Trypsin works in the slightly alkaline conditions of the small intestine (optimum pH of 7.5-8.0).
