Which one of the following mineral elements plays an important role in biological nitrogen fixation : -Biological nitrogen fixation is catalysed by the enzyme nitrogenase, which reduces $N_2$ to $NH_3$.
Nitrogenase is a Mo–Fe protein: molybdenum and iron are essential components of its active site.
Molybdenum is also a component of nitrate reductase, needed for nitrogen assimilation.
So molybdenum plays an important role in biological nitrogen fixation (Mo deficiency reduces nodule activity in legumes).
