Where is the water - splitting complex associated with PS - II situated ?

Options

A. Inner side of chloroplast outer membrane
B. Inner side of thylakoid membrane
C. Outer side of thylakoid membrane
D. Inner side of chloroplast outer membrane

Answer

To solve the question "Where is the water-splitting complex associated with PS-II situated?", we can follow these steps:

### Step 1: Understand the Components
- The water-splitting complex is associated with Photosystem II (PS-II), which is a crucial part of the photosynthetic process in plants.

### Step 2: Identify the Location of PS-II
- Photosystem II is located in the thylakoid membranes of the chloroplasts.

### Step 3: Determine the Specific Location of the Water-Splitting Complex
- The water-splitting complex is specifically involved in the process of photolysis, where water molecules are split into protons, electrons, and oxygen in the presence of light.

### Step 4: Analyze the Options Given
- The options provided are:
1. Inner side of the chloroplast outer membrane
2. Inner side of thylakoid membrane
3. Outer side of thylakoid membrane
4. Inner side of chloroplast outer membrane

### Step 5: Select the Correct Answer
- Since the water-splitting complex is associated with PS-II, which is located on the inner side of the thylakoid membrane, the correct answer is:
**Inner side of thylakoid membrane.**

### Step 6: Conclusion
- The water-splitting complex is indeed situated on the inner side of the thylakoid membrane, where it facilitates the splitting of water during photosynthesis.
