हिन्दीIn the absence of any enzyme, the reaction between \( \text{CO}_2 \) and \( \text{H}_2\text{O} \) produces approximately 200 molecules of \( \text{H}_2\text{CO}_3 \) per hour. When carbonic anhydrase is introduced, about 600,000 molecules are formed every second. By approximately what factor has the reaction rate been accelerated?
Correct answer · Option 3
10 million times
Explanation
Without enzyme: 200 molecules/hour \( \approx 0.055 \) molecules/second. With carbonic anhydrase: 600,000 molecules/second. Acceleration factor \( \approx 600,000 / 0.0555 \approx 10,800,000 \), which is about 10 million times.
