The optimum pH for the functioning of the enzyme pepsin is?
Correct answer: A. 2
- A. 2
- B. 3
- C. 4
- D. 5
Explanation
Pepsin is a protease enzyme, released in the stomach, alongside HCI. Because of HCI, the pH drops to significantly low levels however, this enzyme has adapted to work at maximum efficiency at a pH as low as 2.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
