During non-cyclic photophosphorylation in which of the following , `4e^(-)` produced through photolysis will enter

Options

A. PQ
B. PC
C. PS-II
D. PS-I

Answer

### Step-by-Step Solution:

1. **Understanding Non-Cyclic Photophosphorylation**:
- Non-cyclic photophosphorylation is a process that occurs in the chloroplasts of plants during photosynthesis. It involves the transfer of electrons through a series of proteins and ultimately leads to the production of ATP and NADPH.

2. **Role of Photolysis of Water**:
- Photolysis of water is the process where water molecules (H2O) are split into oxygen (O2), protons (H+), and electrons (e-). This reaction occurs in Photosystem II (PS2) when it absorbs light energy.

3. **Production of Electrons**:
- During the photolysis of water, four electrons (4e-) are produced. These electrons are essential for the continuation of the electron transport chain.

4. **Entry of Electrons**:
- The electrons produced from the photolysis of water enter the electron transport chain starting from Photosystem II (PS2).
- After entering PS2, the electrons are transferred to a series of proteins including plastoquinone (PQ), cytochrome b6f, and plastocyanin (PC), before finally reaching Photosystem I (PS1).

5. **Conclusion**:
- Therefore, the correct answer to the question is that the 4 electrons produced through photolysis will enter **Photosystem II (PS2)**.

### Final Answer:
- The correct option is **C: PS2**.
