Vedclass · Answer

(D) Nitrogen fixation in leguminous plants is primarily carried out by the enzyme nitrogenase,which is present in the root nodules.Cobalt is an essential component of Vitamin $B_{12}$ (cyanocobalamin).Vitamin $B_{12}$ is required for the synthesis of leghemoglobin in the root nodules of leguminous plants.Leghemoglobin acts as an oxygen scavenger,maintaining an anaerobic environment necessary for the activity of the nitrogenase enzyme,which is highly sensitive to oxygen.Therefore,Cobalt is essential for nitrogen fixation in leguminous plants.
