Explanation:
Bacteria
Explanation:
Nitrification fixation takes place by nitrogen-fixing bacteria like Azotobacter, Klebsiella, Bacillus etc which convert atmospheric nitrogen gas into fixed-nitrogen compounds like nitrates or ammonium ions for the plants to readily absorb.
The nitrogen fixing bacteria can be free-living like cyanobacteria or live with symbiotic relationship with plants and fungi.
The chemical conversion of di-nitrogen to ammonia takes place with the help of enzymes like nitrogenase in combination with leghahemoglobin, a protein through a reduction reaction.
Rh proteins; The remainder of the plasma proteins(1%) are regulatory proteins, such asenzymes, proenzymes, and hormones. All blood proteins are synthesized in liver except for the gamma globulins. Separating serum proteins by electrophoresis is a valuable diagnostic tool as well as a way to monitor clinical progress.
