Question: 132 Match List I with List II :
| List I | List II |
|---|---|
| A. Iron | I. Synthesis of auxin |
| B. Zinc | II. Component of nitrate reductase |
| C. Boron | III. Activator of catalase |
| D. Molybdenum | IV. Cell elongation and differentiation |
Choose the correct answer from the options given below :
(1) A-III, B-I, C-IV, D-II
(2) A-II, B-IV, C-I, D-III
(3) A-III, B-II, C-I, D-IV
(4) A-II, B-III, C-IV, D-I
Answer: Option (1)
Explanation:
Iron acts as an activator of enzymes like catalase and peroxidase, so A matches with III.
Zinc is required for the synthesis of auxin by activating enzymes involved in its formation,
so B matches with I.
Boron plays an important role in cell elongation and differentiation,
so C matches with IV.
Molybdenum is a component of the enzyme nitrate reductase,
which is essential for nitrogen metabolism, so D matches with II.
Thus, the correct matching is A-III, B-I, C-IV, D-II.
Hence, Option (1) is the correct answer.
