Vedclass · Answer

(B) Leghemoglobin is an oxygen scavenger found in the root nodules of leguminous plants. The enzyme nitrogenase,which is responsible for biological nitrogen fixation,is highly sensitive to molecular oxygen $(O_2)$. Leghemoglobin creates an anaerobic environment by binding to $O_2$,thereby protecting the nitrogenase enzyme from oxidative damage and ensuring that nitrogen fixation proceeds efficiently.
