NEET2023Biology
Q.
Which micronutrient is required for splitting of water molecule during photosynthesis?
- A
Manganese
- B
Molybdenum
- C
Magnesium
- D
Copper
Solution
The water-splitting (oxygen-evolving) complex at PS II carries a MnCaO cluster. Manganese cycles through several oxidation states to abstract electrons from water, releasing as the byproduct of photosynthesis.
