Mineral elements involved in photolysis of water during Photosynthesis are

Options

A. Mn and Mo
B. Ca and S
C. Mn and CI
D. Ca and Mg

Answer

### Step-by-Step Solution

1. **Understand the Process of Photolysis**:
- Photolysis of water is a light-dependent reaction that occurs during photosynthesis. It involves the splitting of water molecules into oxygen, protons, and electrons.

2. **Identify the Location of Photolysis**:
- This process occurs in the thylakoid lumen of chloroplasts, specifically associated with Photosystem II (PS2).

3. **Determine the Role of Mineral Elements**:
- Certain mineral elements are essential for the photolysis of water. They act as cofactors in the enzymatic reactions that facilitate the splitting of water.

4. **List the Mineral Elements Involved**:
- The key mineral elements involved in the photolysis of water are:
- **Manganese (Mn)**: Essential for the oxygen-evolving complex in Photosystem II.
- **Chlorine (Cl)**: Plays a role in the overall process of photosynthesis and is involved in maintaining the structure of the thylakoid membranes.

5. **Evaluate the Given Options**:
- The options provided are:
- A) Manganese and Molybdenum
- B) Calcium and Sulfur
- C) Manganese and Chlorine
- D) Calcium and Magnesium
- From the analysis, Manganese and Chlorine (Option C) are the correct pair of elements involved in the photolysis of water.

6. **Conclude the Answer**:
- Therefore, the correct answer to the question is **Manganese and Chlorine**.
