Leguminous plants are able to fix atmospheric nitrogen through the process of symbiotic nitrogen fixation. Which one of the following statements is not correct during this process of nitrogen fixation ?
  • a)
    Leghemoglobin scavenges oxygen and is pinkish in colour.
  • b)
    Nitrogenase is insensitive to oxygen.
  • c)
    Nodules act as sites for nitrogen fixation.
  • d)
    The enzyme nitrogenase catalyzes the conversion of atmospheric N2 to NH3.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Leguminous plants are able to fix atmospheric nitrogen through the pr...
1. The enzyme nitrogenase is sensitive to molecular oxygen. The enzyme requires anaerobic conditions during nitrogen fixation, but live as aerobes under free-living conditions.
2. Leg-hemoglobin provides anaerobic condition to the enzyme nitrogenase. It protects the enzyme from oxygen. It scavenges oxygen and is pinkish in colour.
3. As nodules contain necessary biochemical components so that helps in fixing atmospheric nitrogen to ammonia. They act like sites of nitrogen fixation.
4. The enzyme nitrogenase catalyzes the conversion of atmospheric nitrogen to ammonia. It requires 8 ATP. The energy obtained from the respiration of the host plant.
Thus, the correct answer is option B.
