What chemical transformations are catalzyed by the enzyme i) catalase and ii) nitrogenase


confused, please help!

In nitrogen-fixing microorganisms, nitrogenase catalyzes the conversion of nitrogen to ammonia.

Catalase accelerates the breakdown of H2O2 into H2O and O2, in cells. H2O2 is a poisonous byproduct of metabolism
