The optimum pH for enzyme arginase is?
Correct answer: C. 9.7
- A. 9
- B. 9.3
- C. 9.7
- D. 10
Explanation
The optimum pH of arginase is typically around 9.5-10.5. Arginase is an enzyme that catalyzes the hydrolysis of arginine to ornithine and urea. The optimum pH for arginase activity can vary depending on the specific type of arginase and the organism it comes from. Generally, arginase is active in a slightly alkaline pH range.In humans, for example, arginase I, which is primarily found in the liver, has an optimum pH around 9.5. On the other hand, arginase II, found in other tissues, may have a slightly different optimum pH.

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.
