Biological nitrogen fixation probably occurs via the binding of N2 to a metal center in the enzyme nitrogenase, followed by a series of steps that involve electron transfer and protonation.
Fiksasi nitrogen biologis mungkin terjadi melalui pengikatan N2 ke pusat logam di dalam enzim nitrogenase, diikuti oleh serangkaian langkah yang melibatkan transfer elektron dan protonasi.
