Question

$N_2+8e^{-}+8H^{+}+16ATP\to 2N{H}_3+H_2+16ADP+16Pi$
The above equation refers to

• A. Ammonification
• B. Nitrification
• C. Nitrogen fixation
• D. Denitrification
• E. Reductive amination

Answer 1

Answer: (C)

Nitrogen fixation

The above equation represents nitrogen fixation because free gaseous nitrogen reacts chemically to give ammonium ions. It is a reduction reaction, wherein free nitrogen, which was unavailable to plants has been reduced to usable ammonia. This reaction is catalyzed by enzyme nitrogenase and occurs in root nodules of leguminous plants.

So, the correct answer is option C.
