Optimum pH of enterokinase is:
Correct answer: A. Slightly acidic
- A. Slightly acidic
- B. Slightly basic
- C. Highly acidic
- D. Highly basic
Explanation
Enterokinase has an optimal pH of 5.5, which classifies it as slightly acidic. This pH is essential for its enzymatic activity in the small intestine, where it activates trypsinogen into trypsin, facilitating protein digestion. The other options are incorrect because:Slightly basic: This option is incorrect because a pH of 5.5 is acidic, not basic.Highly acidic: This option misrepresents the pH since a pH of 5.5 is not highly acidic, which would be below pH 3.0.Highly basic: This option is also incorrect because a pH of 5.5 does not fall in the basic range, as it is below neutral (7.0).

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.
