(a) The enzyme responsible for nitrogen fixation is known as nitrogenase. Nitrogenase enzyme complex consists of two components, i.e., Fe-protein and Mo-Fe protein. The subunits of Fe-protein contain iron-sulphur cluster (4 Fe and 4S) that participates in the redox reactions involved in the conversion of nitrogen to ammonia. |
