Question:
Which of the following is function of Molybdenum?
Which of the following is function of Molybdenum?
Show Hint
Molybdenum is part of nitrogenase and nitrate reductase, enzymes of nitrogen metabolism.
Updated On: Nov 12, 2026
- Activates carboxylase enzyme
- Required for uptake and utilisation of \(\text{Ca}^{2+}\)
- Activates enzyme in the nitrogen metabolism
- Activates enzyme in phosphate metabolism
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Molybdenum is a micronutrient needed by plants in very small amounts.
Step 2: Role
It is a component of nitrogenase, which fixes nitrogen, and nitrate reductase, which reduces nitrate. Both belong to nitrogen metabolism.
Step 3: Other options
Boron is needed for uptake and use of \(\text{Ca}^{2+}\). Carboxylase is activated by zinc.
Final Answer:
Molybdenum activates enzymes in nitrogen metabolism. \[ \boxed{\text{(C) }\text{Activates enzyme in the nitrogen metabolism}} \]
