Verified Answer
In the following question, a statement of Assertion(A) is given follow...
Symbiotic nitrogenfixation occurs in lgume plants.It takes place in the Rhizobium bacteroids which are located within root nodules cells.Rhizobium is an aerobic bacteria and hence it survives in presence of oxygen. But the important enzyme nitrogenase that reduces N2 is oxygen sensitive. It can only function at low oxygen concentration. This low concentration of oxygen in bacteroid is provided by leghaemoglobin.
Leghaemoglobin is a form of haemoglobin found in the nitrogen fixing root nodules of legume.They bound oxygen and thus protect the nitrogen fixing enzyme, nitrogenase. It regulates oxygen diffusion to bacteroids and nitrogenase.
