  • nitrogen metabolic cycle, reducing nitrogen to ammonium;
  • plants and other microorganisms, nitrates and nitrites into amino acids;
  • animals and plant foods, adenosine deaminase in amino acid deamination;
  • human activity, effects on nitrogen cycle leading to overdenitrification;
  • nitrous oxide, greenhouse gas, and global warming/climate change;
  • nitrate concentration more than 10 mg N/l of water, threats to public health;
  • purine and pyrimidine nucleotide synthesis and PRPP, nitrogen donors;
  • nitrogenase regulation by fixed nitrogen, and ATP nitrogen;
