Compare reactions of nitrogen fixation and nitrogen assimilation
Accepted Answer
Nitrogen fixation and nitrogen assimilation are both crucial steps in the nitrogen cycle, but they differ in their processes and products:
Nitrogen Fixation:
Process: Conversion of atmospheric nitrogen gas (N2) into ammonia (NH3) by certain microorganisms (nitrogen-fixing bacteria).
Location: Occurs in specialized enzymes, like nitrogenase, found in these bacteria.
Product: Ammonia (NH3)
Nitrogen Assimilation:
Process: Incorporation of inorganic nitrogen (ammonia, nitrate) into organic molecules, like amino acids, by organisms.
Location: Occurs in various cellular processes, including the synthesis of amino acids.
Product: Organic nitrogen compounds (amino acids, proteins, nucleic acids)
