Vedclass · Answer

(A) The enzyme nitrogenase,which is responsible for biological nitrogen fixation,is a $Mo-Fe$ protein. Similarly,nitrate reductase,an enzyme involved in the reduction of nitrate to nitrite in plants,also requires molybdenum $(Mo)$ as a crucial cofactor for its activity. Therefore,molybdenum is a common essential component for both nitrogenase and nitrate reductase enzymes.
