Match the following and choose the correct combination from the options. Column –I Column – II A Potassium (i) Constituent of ferredoxin B Sulphur (ii) Involved in stomatal movement C Molybdenum (iii) Auxin synthesis D Zinc (iv) Component of nitrogenase
Options
- AA-ii, B-i, C-iv, D-iii
- BA-i, B-ii, C-iii, D-iv
- CA-iv, B-iii, C-ii, D-i
- DA-ii, B-iii, C-iv, D-i
Correct answer
A. A-ii, B-i, C-iv, D-iii
Step-by-step solution
Potassium maintains cation and anion balance and it regulates the movement of the stomata. Sulphur is a constituent of amino acid, ferredoxin, and some vitamins. Molybdenum is a constituent of the enzyme nitroganase that is necessary during nitrogen fixation process. Zinc is an activator of the enzyme tryptophan synthetase which is necessary for the synthesis of auxin.
