One molecule of carbonic anhydrase can hydrate up to a million molecules of carbon dioxide every second. This demonstrates the enzyme's
- A. instability at body temperature
- B. gradual consumption during the reaction
- C. very high turnover number
- D. resistance to all inhibitors
Explanation
The turnover number is how many substrate molecules one enzyme molecule converts per second, and carbonic anhydrase has one of the highest known. The enzyme itself is unchanged and reused, so the huge rate reflects catalytic power, not consumption.
