Splitting of water is associated with

Options

A. photosystem I
B. lumen of thylakoid
C. both photosystem I and II
D. inner surface of thylakoid membrane

Explanation

**Step-by-Step Solution:**

1. **Understanding Photolysis of Water:**
- The process of splitting water into hydrogen and oxygen is known as photolysis. This occurs during photosynthesis in chloroplasts.

2. **Role of Light:**
- Light energy is absorbed by chlorophyll, which energizes electrons. This energy is crucial for the photolysis reaction.

3. **Location of Water Splitting:**
- The splitting of water occurs in the thylakoid membranes of chloroplasts. Specifically, it is associated with the photosystems (Photosystem I and II).

4. **Enzymatic Action:**
- An enzyme complex catalyzes the photolysis of water. This complex is located in the thylakoid membrane, where the photosystems are embedded.

5. **Products of Photolysis:**
- The photolysis of water results in the formation of hydrogen ions, electrons, and oxygen. The oxygen produced is released into the atmosphere.

6. **Conclusion:**
- Therefore, the splitting of water is primarily associated with the inner surface of the thylakoid membrane.

**Final Answer:**
The splitting of water is associated with the inner surface of the thylakoid membrane.
