2 Nitrification Reactions
First Stage: Conversion of free ammonia to nitrite Second Stage: Conversion of nitrite to nitrate Combined Reaction Return

3 First Stage Nitrification Reactions
First Step: Conversion of free ammonia to hydroxylamine: AMO: Ammonia monooxygenase, membrane bound enzyme Second Step: Conversion of hydroxylamine to nitrite: HAO: Hydroxylamine oxidoreductase, located in the periplasmic space Third Step: Abiotic oxygen reduction: AMO HAO Return
