WebAnd like carbon and oxygen, it cycles through our biosphere. Now, one thing that's maybe surprising about nitrogen, if you haven't studied it much, is that it is very, very common in our atmosphere. 78% of our atmosphere is molecular nitrogen, so it's in the form of N2. So this right over here is molecular nitrogen. Webwhile N2is bound to the nitrogenase enzyme complex. The Fe protein is first reduced by electrons donated by ferredoxin. Then the reduced Fe protein binds ATP and reduces the molybdenum-iron protein, which donates electrons to N2, producing HN=NH. In two further cycles of this process (each requiring
