For its action, nitrogenase requires

  • high input of energy

  • light

  • Mn2+

  • super oxygen radicals

Answer

A.

high input of energy

The enzyme nitrogenase is a Mo-Fe protein and catalyses the conversion of atmospheric N2 to NH3 as
straight N subscript 2 plus 8 straight e to the power of minus plus 8 straight H to the power of plus plus 16 ATP space rightwards arrow space 2 NH subscript 3 plus straight H subscript 2 plus 16 ADP plus 16 straight P subscript straight i
Enzyme nitrogenase functions under anaerobic condition and the pigment leghaemoglobin protect it from oxygen.
