Answer:
1. The enzyme nitrogenase is sensitive to molecular oxygen. The enzyme requires anaerobic condition during nitrogen fixation, but live as aerobes under free-living conditions.
2. Leg-haemoglobin 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 catalyses the conve
rsion of atmospheric nitrogen to ammonia. It requires 8 ATP. The energy obtained from the respiration of the host plant.
