Nitrogenase Enzyme

An enzyme complex responsible for the reduction of atmospheric nitrogen to ammonia, a critical step in the nitrogen fixation process.

Nitrogen Cycle

The biogeochemical cycle that describes the movement and transformation of nitrogen through the atmosphere, living organisms, and soil.
