The function of leghaemoglobin in the root nodules of legumes is
The function of leghaemoglobin in the root nodules of legumes is
Updated On: Aug 20, 2024
- inhibition of nitrogenase activity
- oxygen removal
- nodule differentiation
- expression of nif gene
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The root nodule of legume contains enzyme $1$ nitrogenase and leg haemoglobin. Nitrogenase catalyses the conversion of atmospheric nitrogen to ammonia. It is highly sensitive to the molecular oxygen and requires anaerobic conditions. The nodules have adaptations that ensure that the enzyme is protected from oxygen. To protect these enzymes, the nodule contains an oxygen scavenger called leg haemoglobin.

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:
