Photolysis of water is important event of light reaction of photosynthesis.Read the following statements and choose the correct statement(s).
Water splitting complex splits water into `OH^- + H^+`. It is associated with photosystem-II.
Water splitting Complex and photosystem-II both are present on the outer side of the thylakoid membrane.

Options

A. I is incorrect
B. I is correct
C. Both are incorrect
D. Both are correct

Answer

To solve the question regarding the photolysis of water in the light reaction of photosynthesis, we need to analyze the two statements provided:

1. **Statement 1**: "Water splitting complex splits water into `OH^- + H^+`. It is associated with photosystem-II."
2. **Statement 2**: "Water splitting Complex and photosystem-II both are present on the outer side of the thylakoid membrane."

### Step-by-Step Solution:

**Step 1: Understand the process of photolysis of water.**
- Photolysis of water refers to the splitting of water molecules into oxygen, protons (H^+), and electrons (e^-) during the light-dependent reactions of photosynthesis.
- The reaction can be summarized as:
\[ 2 H_2O \rightarrow 4 H^+ + 4 e^- + O_2 \]

**Step 2: Analyze Statement 1.**
- The first statement claims that the water splitting complex produces `OH^-` and `H^+`. However, the correct products of the photolysis of water are protons (H^+) and oxygen (O_2), not hydroxide ions (OH^-).
- The water splitting complex is indeed associated with photosystem II, which is correct.

**Step 3: Analyze Statement 2.**
- The second statement claims that both the water splitting complex and photosystem II are located on the outer side of the thylakoid membrane.
- In reality, both the water splitting complex and photosystem II are located on the inner side of the thylakoid membrane, not the outer side.

**Step 4: Conclusion.**
- Based on the analysis:
- Statement 1 is partially correct because it correctly associates the water splitting complex with photosystem II but incorrectly states the products of the reaction.
- Statement 2 is incorrect as it misstates the location of the water splitting complex and photosystem II.

Thus, the correct answer is that **only Statement 1 is correct**.

### Final Answer:
- **Correct Statement(s)**: Statement 1 is correct.
