Text Solution

Verified by Experts

The correct Answer is:
A
During biological nitrogen fixation, inactivation of nitrogenase by oxygen posioning is prevented by leghaemoblocin. It is a red-pigment that is filled ouside the peribacteroid space In the cytosol of nodule cells. It is similar to haemoglobin of red blood cells. it has the ability of combine very rapidly with oxygen and thus acts as a very efficient `O_(2)` scavenger.
