Question

Match the following:

$\begin{array}{cc}\text{Column - I}& \text{Column - II}\\ \text{A. Manganese}& \text{1. Involved in Electron Transport}\\ \text{B. Copper}& \text{2. Role in Nitrogen Fixation}\\ \text{C. Boron}& \text{3. Photolysis of Water}\\ \text{D. Molybdenum}& \text{4. Maintenance of Ionic Balance in Cells}\\ & \text{5. Required for Pollen Germination}\end{array}$

• A. A - 3, B - 1, C - 5, D - 4.
• B. A - 2, B - 1, C - 5, D - 3
• C. A - 3, B - 1, C - 5, D - 2
• D. A - 3, B - 1, C - 2, D - 5

Answer 1

The correct option is C

A - 3, B - 1, C - 5, D - 2

The best-defined function of Mn is in the splitting of water to liberate oxygen during photosynthesis. Copper is involved in the electron transport during aerobic respiration. Boron is required for pollen germination. Molybdenum is a component of enzyme nitrogenase which is required for nitrogen fixation.
