The enzyme nitrogenase is

Options

  1. AA Cu-Fe protein
  2. BFound in prokaryotes only
  3. CAn O 2 requiring enzyme
  4. DEssential to convert NH 3 to N 2

Correct answer

B. Found in prokaryotes only

Step-by-step solution

The enzyme complex nitrogenase consists of two subunits: (i) A non-heme iron protein commonly called Fe protein (or dinitrogen reductase, component I). (ii) An iron-molybdenum protein called MoFe protein (or dinitrogenase, component II). It is found in prokaryotes only and functions under anaerobic conditions.
