Question: 123: Match List -I with List – II
| List -I | List -II |
|---|---|
| (a) Manganese | (i) Activates the enzyme catalase |
| (b) Magnesium | (ii) Required for pollen germination |
| (c) Boron | (iii) Activates enzymes of respiration |
| (d) Iron | (iv) Function in splitting of water during photosynthesis |
Choose the correct answer from the options given below :
(1) (a)-(vi), (b)-(i), (c)-(ii), (d)-(iii)
(2) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
(3) (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
(4) (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
Answer: Option (4)
Explanation:
Manganese plays a crucial role in photosynthesis by being a component of the oxygen-evolving complex and is involved in the splitting of water, so (a) matches with (iv).
Magnesium acts as an activator of many enzymes involved in respiration and is also a central atom of chlorophyll, hence (b) matches with (iii).
Boron is essential for pollen germination and pollen tube growth,
so (c) matches with (ii).
Iron is required for the activation of enzymes like catalase and peroxidase,
therefore (d) matches with (i).
Thus, the correct matching corresponds to Option (4).
