Question

Quizplus · Accepted Answer

Nitrogen fixation involves adding hydrogen ions to nitrogen gas (N2) in three successive pairs to form ammonia (NH3). This process is catalyzed by the enzyme nitrogenase, and it requires a lot of energy in the form of ATP. Option A is incorrect because only one bond is broken at a time. Option C is incorrect because a significant amount of energy is required. Option D is incorrect because nitrogenase catalyzes all of the reactions. Option E is incorrect because nitrogen fixation is actually inhibited by high oxygen concentrations.
