Centre of phosphorylation is

Options

A. Ribosome
B. Oxisome
C. Peroxisome
D. Spherosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the center of phosphorylation. We need to identify which of the given options is primarily involved in the process of phosphorylation, particularly oxidative phosphorylation.

2. **Reviewing the Options**: The options provided are:
- Ribosomes
- Oxysomes
- Peroxisomes
- Spherosomes

3. **Analyzing Each Option**:
- **Ribosomes**: These are the sites of protein synthesis in the cell. They do not play a direct role in phosphorylation. Therefore, this option is incorrect.

- **Oxysomes**: Also known as F0-F1 particles, these structures are located in the inner mitochondrial membrane, specifically in the folds called cristae. They are directly involved in the process of oxidative phosphorylation, where ATP is produced through the transfer of electrons. This makes this option correct.

- **Peroxisomes**: These organelles are involved in various oxidative reactions and play a role in metabolism, but they are not directly related to phosphorylation. Thus, this option is incorrect.

- **Spherosomes**: These are small organelles that are involved in lipid storage and synthesis. They do not participate in phosphorylation processes. Therefore, this option is also incorrect.

4. **Conclusion**: After analyzing all options, we conclude that the center of phosphorylation is **Oxysomes**.

**Final Answer**: The center of phosphorylation is **Oxysomes**.
