NEET Biology question

Not in NEET syllabus

Which of the following reactions shows nitrogen fixation?

(A)2NH4+ + 2O2 + 8e− → N2 + 4H2O
(B)2NH3 → N2 + 3H2
(C)N2 + 4H2 → 2NH3Correct
(D)2N2 + Glucose → 2 Amino acids

Answer: (C)

Solution

Nitrogen fixation is the reduction of atmospheric dinitrogen to ammonia, consuming hydrogen (electrons/protons) in the process — represented here (in simplified form) as N2 + 4H2 → 2NH3, mirroring the real nitrogenase reaction's
