The enzyme nitrogenase is
The enzyme nitrogenase is
Options
- AA Cu-Fe protein
- BFound in prokaryotes only
- CAn O_{2} requiring enzyme
- 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.
