Dinitrogenase (formerly called nitrogenase) is just one enzyme of several involved with the fixation of nitrogen. Nitrogen is reduced from one molecular nitrogen to two ammonia molecules within the Fe-Mo-co (Iron-Molybdenum complex) of dinitrogenase. This process requires a total of 8 electrons; 6 electrons are used directly to reduce nitrogen and 2 other electrons are used for the formation of molecular hydrogen from two protons. The purpose of the latter use of electrons is unknown.
