Nitrogen constitutes the major component (approximately 78%) with oxygen following at about 21%, and carbon dioxide at 0.04%. Though carbon dioxide constitutes a minor part of the atmosphere, life, as we … WebbBiological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by an enzyme called nitrogenase. The reaction for BNF is: 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 reaction. The exact mechanism of catalysis is ...
