Question

Molybdenum is related with

• A. N${}_2$ fixation
• B. Flower induction
• C. Chromosome contraction
• D. Carbon collection

Answer 1

The correct option is A N${}_2$ fixation

Molybdenum is the mineral required for nitrogen fixation by nitrogenase enzyme. During reduction process the nitrogenase provides electrons to nitrogen in stages i.e., sequentially electrons are passed on to nitrogen. For this purpose the ability of molybdenum to exist in variable oxidation states is suitable. Thus, nitrogenase is a molybdo flavoprotein.

So, the correct answer is option A.
