Solution(By Examveda Team)

Molybdenum plays a major role in Nitrogen fixation.
Mo is the component of meta-protein nitrogenase which helps the process of biological nitrogen fixation and acts as an essential component needed for N bacteria metabolism. The nitrogenase enzyme needs the Mo element in the process of its metabolism, which acts as an electron carrier between the oxidized and reduction stages.
