In the mechanism of nitrogen reduction, __________ directly takes the place of the H₂in the FeMo subunit of the enzyme nitrogenase. A) NH₃ B) N₂ C) HN=NH D) H₂N-NH₂ E) any of the above

Question

Quizplus · Accepted Answer

The mechanism of nitrogen reduction involves nitrogenase, which contains a FeMo cofactor that has an ₂ ligand. During the reaction, the ₂ ligand is replaced by the nitrogen molecule (N2) to form a complex. Therefore, the nitrogen molecule directly takes the place of the ₂ ligand, making choice B the correct answer. The other options do not accurately describe this substitution process.
