Electron acceptor of PS `II` is

Options

A. Cyt b
B. FRS
C. PQ
D. `NADP^(+)`

Answer

To answer the question regarding the electron acceptor of Photosystem II (PS II), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosystem II (PS II)**:
- PS II is a crucial component of the photosynthetic process, where it absorbs light energy to excite electrons.

2. **Light Absorption**:
- When light energy strikes PS II, it energizes electrons, causing them to move to a higher energy state.

3. **Electron Transfer**:
- The excited electrons from PS II are transferred to a series of proteins and molecules in the electron transport chain.

4. **Identifying the First Electron Acceptor**:
- The first molecule that accepts the excited electrons from PS II is known as plastoquinone (PQ).

5. **Role of Plastoquinone**:
- Plastoquinone captures the electrons and then passes them on to the cytochrome b6f complex, which further facilitates the transfer of electrons down the chain.

6. **Conclusion**:
- Therefore, the electron acceptor of PS II is plastoquinone (PQ).

### Final Answer:
The electron acceptor of PS II is **plastoquinone (PQ)**.
