`F_(1)` subunit of oxysome is called :-

Options

A. Head
B. Stalk
C. Base
D. Filament

Answer

To answer the question about what the F1 subunit of oxysome is called, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Oxysome**:
- Oxysomes, also known as ATP synthase complexes, are structures found on the inner membrane of mitochondria. They play a crucial role in the synthesis of ATP (adenosine triphosphate), which is the energy currency of the cell.

2. **Identifying the Subunits**:
- The oxysome is composed of two main parts: the F0 and F1 subunits. The F0 subunit is embedded in the membrane, while the F1 subunit protrudes into the mitochondrial matrix.

3. **F1 Subunit**:
- The F1 subunit is often referred to as the "head" of the oxysome. It is responsible for the catalytic activity of ATP synthesis.

4. **Evaluating Options**:
- The options provided are:
1. Head
2. Stalk
3. Base
4. Filament
- Based on our understanding, the F1 subunit corresponds to the "head" of the oxysome.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the F1 subunit of the oxysome is called the **Head**.

### Final Answer:
The F1 subunit of oxysome is called **Head**.
