WebMar 14, 2024 · Learning Objectives. Biological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by an enzyme called nitrogenase. The reaction for BNF is: (4.15C.1) N 2 + 8 H + + 8 e − → 2 NH 3 + H 2. This type of reaction results in N 2 gaining electrons (see above equation) and is thus termed a reduction … WebBiological nitrogen fixation, the conversion of dinitrogen (N 2) into ammonia (NH 3), stands as a particularly challenging chemical process.As the entry point into a bioavailable form of nitrogen, biological nitrogen fixation is a critical step in the global nitrogen cycle.
