The electrons released during splitting of water are used to replace electrons removed from

Options

A. PS-I
B. PS-II
C. Cytochrome complex
D. NADP reductase complex

Answer

To solve the question, "The electrons released during the splitting of water are used to replace electrons removed from," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Water Splitting**: Water splitting occurs during the light-dependent reactions of photosynthesis, specifically at a complex known as the oxygen-evolving complex (OEC). This process generates electrons, protons, and oxygen.

2. **Identifying the Role of Photosystems**: In photosynthesis, there are two main photosystems: Photosystem II (PSII) and Photosystem I (PSI). PSII is responsible for capturing light energy and initiating the process of electron transport.

3. **Electron Flow in Photosystems**: When light energy is absorbed by PSII, it excites electrons, which are then ejected from the reaction center of PSII. This creates an electron deficiency in PSII that needs to be replenished.

4. **Replacement of Electrons**: The electrons released from the splitting of water are specifically used to replace the electrons that have been lost from PSII. This is crucial for maintaining the flow of electrons through the photosynthetic electron transport chain.

5. **Conclusion**: Therefore, the electrons released during the splitting of water are used to replace the electrons removed from Photosystem II.

### Final Answer:
The electrons released during the splitting of water are used to replace electrons removed from **Photosystem II**.
