The enzyme ________ converts nitrogen into ammonia.

Question

Quizplus · Accepted Answer

The enzyme nitrogenase is responsible for converting atmospheric nitrogen gas into ammonia, which is then used by plants to synthesize amino acids and proteins. Option A (oxygenase) is incorrect because it converts oxygen, not nitrogen, into a different molecule. Option B (hydrogenase) catalyzes the oxidation of molecular hydrogen into protons and electrons. Option C (oxidase) is too broad, as there are many different kinds of oxidases that catalyze various oxidation reactions. Option D (nitroglycerine) is a chemical explosive and is not an enzyme involved in biological nitrogen fixation.
