Biological fixation of nitrogen is helped by
A. Zinc
B. Copper
C. Boron
D. Molybdenum
Answer: Option D
Solution (By Examveda Team)
The biological fixation of nitrogen is helped by Molybdenum.Molybdenum (Mo), an essential micronutrient, plays an important role in nitrogen (N) metabolism and protein synthesis in plants.
During symbiotic N fixation, Mo acts as a cofactor for nitrogenase enzymes to catalyze the redox reaction to convert elemental N into ammonium (NH4+) ions.
