Which of the following is a requirement of all N₂-fixing systems?

Question

Quizplus · Accepted Answer

The enzyme nitrogenase is required for all N₂-fixing systems. This enzyme is responsible for reducing nitrogen gas into ammonia, which is then used by plants and other organisms for various cellular processes. While other factors may be involved in the process of nitrogen fixation, such as GTP or a strong oxidizer, the presence of nitrogenase is essential. H₂O-free conditions may also be necessary for some nitrogen-fixing bacteria, but this is not a universal requirement for all systems.
