A.
Zinc
B.
Copper
C.
Boron
D.
Molybdenum
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
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.
