Nitrogen Metabolism (Prokaryotes)

Question 1

what is nitrogen used for?

Answer 1

production of amino and nucleic acids in all organisms

Question 2

Where do eukaryotic cells obtain N2 from?

Answer 2

a limited group of nitrogen compounds

Question 3

where do prokaryotic cells obtain N2 from?

Answer 3

metabolised in many forms (e.g. some cyanobacteria and methanogens convert atmospheric nitrogen into amonia (NH3).

Question 4

Nitrogen Fixation

Answer 4

The process of converting atmospheric nitrogen into ammonia. The cells can then incorporate this fixed N into amino acids and other organic molecules
