In nitrogen-fixing bacteria, the nitrogenase complex is sensitive to:
Correct answer: A. O2
- A. O2
- B. CO2
- C. NO2
- D. NO3
Explanation
Nitrogen fixing bacteria contain an enzyme complex known as Nitrogenase which catalyses the conversion of nitrogen gas to ammonia. The nitrogenase complex is sensitive to oxygen. Oxygen will make the enzyme irreversibly inactive. So, the nitrogen-fixing bacteria needs to protect the nitrogenase enzyme from oxygen.
