Question

What are the oxygen scavengers found in nodules called which protect enzymes?

Answer 1

Oxygen scavengers in nodules:

1. The legume-bacteria relationship is the first necessary condition for nitrogen fixation.
2. Rhizobium bacteria are responsible for the formation of nodules in this association.
3. Nitrogenase is extremely sensitive to molecular oxygen.
4. Leghaemoglobin, an oxygen scavenger, protects these enzymes from oxygen in the nodule.
5. Rhizobium bacteria live freely in soil. They are nitrogen-fixing symbionts that can fix atmospheric nitrogen for plants.
