N2 + 16ATP + 8e- + 8H+ -> 2NH3 + H2 + 16ADP + 16Pi. Geedi socodka waxaa lala xiriiriyaa biyo-ku-darista 16 oo u dhiganta ATP waxaana weheliya isku-dhafka hal u dhiganta H2. Is-beddelka N2 ee ammonia wuxuu ka dhacaa koox bir ah oo la yiraahdo FeMoco, oo ah soo gaabinta birta-molybdenum cofactor. Farsamadu waxay ku dhacdaa taxane taxane ah oo ah protonation iyo hoos-u-dhigista tallaabooyinka halkaas oo goobta firfircoon ee FeMoco ay hydrogenates N2 substrate. In dia-biyo xor ah, ammonia-ka loo yaqaan 'nitrogenase-ka' waxaa lagu dhex geliyaa glutamate iyada oo loo marayo glutamine synthetase / glutamatase. Waddooyinka microbial-ka loo baahan yahay ee loo yaqaan 'nitrogen fixation pathway' ayaa si ballaaran loogu qaybiyaa deegaanno kala duwan sida bakteeriyada. Sababtan awgeed, waxaa jira
