Elementary particles of mitochondria are :-

Options

A. `F_(1)` particles
B. Ribosomes
C. DNA
D. Lysosomes

Answer

To answer the question "Elementary particles of mitochondria are:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mitochondria Structure**:
- Mitochondria are double-membraned organelles found in eukaryotic cells. They are known as the powerhouse of the cell because they generate ATP through cellular respiration.

2. **Identifying Elementary Particles**:
- The term "elementary particles" in the context of mitochondria refers to the components involved in ATP synthesis.

3. **F1 Particles**:
- The F1 particles are a part of the ATP synthase complex located in the inner mitochondrial membrane. They are crucial for the synthesis of ATP from ADP and inorganic phosphate during oxidative phosphorylation.

4. **Evaluating Other Options**:
- **Ribosomes**: These are not specific to mitochondria; they are involved in protein synthesis in all cells.
- **DNA**: While mitochondria contain their own DNA, it is not classified as an elementary particle.
- **Lysosomes**: These are involved in digestion and waste removal in cells and are not related to mitochondria.

5. **Conclusion**:
- Based on the analysis, the correct answer to the question is that the elementary particles of mitochondria are **F1 particles**.

### Final Answer:
**F1 particles**
