Which of the following describes the process of nitrogen fixation?

Question

Quizplus · Accepted Answer

Nitrogen fixation is the process of converting nitrogen gas (N₂) into ammonia (NH₃) or ammonium ions (NH₄⁺). This process can be carried out by certain bacteria, either free-living in the soil or in a symbiotic relationship with plants. These bacteria use an enzyme called nitrogenase to break the strong triple bond between the nitrogen atoms in N₂ and combine them with hydrogen ions (H⁺) to form ammonia or ammonium ions.
