Mineals involved in photooxidation of water are

Options

A. Mn, Cl, Ca
B. Mg, Fe, Mn
C. Mn, Fe, Ca
D. N,P,K

Answer

**Step-by-Step Solution:**

1. **Understanding Photo-oxidation of Water:**
- Photo-oxidation refers to the process in which water molecules are split into oxygen, protons, and electrons using light energy. This process is essential in photosynthesis, particularly in the light-dependent reactions.

2. **Identifying the Minerals Involved:**
- The minerals that play a crucial role in the photo-oxidation of water are:
- **Manganese (Mn):** It is essential for the water-splitting complex in photosystem II.
- **Chlorine (Cl):** It is involved in the stabilization of the water-splitting complex.
- **Calcium (Ca):** It helps in maintaining the structure of the photosystem and is involved in the signaling processes.

3. **Analyzing the Options:**
- **Option 1:** Manganese, Chlorine, Calcium - This is correct as these minerals are directly involved in the photo-oxidation of water.
- **Option 2:** Magnesium, Iron, Manganese - This is incorrect because while magnesium is important for chlorophyll, it is not directly involved in the photo-oxidation of water.
- **Option 3:** Manganese, Iron, Calcium - This is incorrect because chlorine is missing, which is essential for the process.
- **Option 4:** NPK (Nitrogen, Phosphorus, Potassium) - This is incorrect as these are macronutrients for plant growth but not specifically involved in the photo-oxidation of water.

4. **Conclusion:**
- The correct answer is **Option 1: Manganese, Chlorine, Calcium**. These minerals are essential for the photo-oxidation of water during photosynthesis.
