Total no. of electron consumed per unit N₂ fixation during BNF is

Solution (By Examveda Team)

The total number of electrons consumed per unit of nitrogen fixation during Biological Nitrogen Fixation is 8.
The overall reaction for the net formation of 2NH₃ from one N₂ is:
N₂ + 8H⁺ + 8e⁻ + 16ATP + 16H₂O ⟶ 2NH₃ + H₂ + 16ADP + 16Pi
That shows nitrogen element takes 8 hydrogen ions and 8 electrons along with 16 molecules of ATP and water to produce 2 molecules of NH₃.
