Correct answer: B. Slightly alkaline
- A. Neutral
- B. Slightly alkaline
- C. Highly acidic
- D. Highly alkaline
Explanation
Enterokinase (also called enteropeptidase) functions best in a slightly alkaline environment, typically around pH 7.5-8.0, which is characteristic of the intestinal lumen where it activates trypsinogen to trypsin.

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.
