B. `10^2 -10^3`
C. `10^6-10^8`
D. `10^8 -10^9`

Answer

To determine the number of oxysomes (F0, F1 particles) per mitochondrion, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Oxysomes**:
- Oxysomes, also known as F0, F1 particles, are structures found in the mitochondria that play a crucial role in ATP synthesis.

2. **Structure of Oxysomes**:
- The oxysome consists of two parts:
- The F1 portion, which is rounded and faces the mitochondrial matrix.
- The F0 portion, which acts as a proton pump and is embedded in the inner mitochondrial membrane.

3. **Function of Oxysomes**:
- The F0 particle facilitates the movement of protons, while the F1 particle is responsible for synthesizing ATP from ADP and inorganic phosphate (Pi).

4. **Importance of Number**:
- The number of oxysomes is directly related to the mitochondrion's ability to produce ATP. More oxysomes mean more ATP can be synthesized.

5. **Average Number of Oxysomes**:
- Research indicates that the average number of oxysomes per mitochondrion is approximately between \(10^4\) to \(10^5\) (10,000 to 100,000).

6. **Conclusion**:
- Therefore, the number of oxysomes per mitochondrion is \(10^4\) to \(10^5\).

### Final Answer:
The number of oxysomes per mitochondrion is approximately \(10^4\) to \(10^5\).
