Q872
Total no. of electron consumed per unit N2 fixation during BNF is
A.
6
B.
8
AnswerC.
12
D.
16
Answer: Option B
Solution
Answer: Option B
Solution:
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.
