"Dinitrogenase" Natural Recordings by Native Speakers
Dinitrogenase is an enzyme that plays a crucial role in nitrogen fixation, which is the process by which atmospheric nitrogen (N2) is converted into a form that can be used by living organisms. Dinitrogenase is a complex enzyme that consists of multiple subunits and is responsible for catalyzing the reduction of N2 to two nitrogen atoms. This broken bond allows the nitrogen to be used by microorganisms, plants, and animals for growth and development.
