Which of the following observations most strongly support the view that mitochondria contain transport enzymes aggregated into compact association ?

Options

A. Mithochondria have a property to concentrate in cells which form locomotory structres.
B. Disruption of mitochondria yields membrane fragments which are able to syntesize ATP.
C. Mitochondria have a folded inner membrane.
D. A contractile protein capable of utilizing ATP is obtained from mitochondria

Answer

To determine which observation most strongly supports the view that mitochondria contain transport enzymes aggregated into compact associations, we can analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding the Role of Mitochondria**:
- Mitochondria are known as the powerhouse of the cell, primarily responsible for ATP production through cellular respiration. They contain various enzymes, including transport enzymes, which are crucial for their function.

2. **Evaluating Each Option**:
- **Option 1**: "Mitochondria have a property to concentrate in cells which form the locomotory structures."
- This option discusses the concentration of mitochondria in sperm cells, which is related to energy production for locomotion. However, it does not directly address the presence of transport enzymes, making it less relevant.

- **Option 2**: "Disruption of the mitochondria leads to membrane fragments that are able to synthesize ATP."
- This option indicates that even when mitochondria are disrupted, the membrane fragments can still synthesize ATP, which involves the cytochrome chain. The cytochrome chain consists of transport proteins that facilitate the movement of ions (H+ ions), supporting the idea of aggregated transport enzymes. This is a strong indication of the presence of transport enzymes in mitochondria.

- **Option 3**: "Mitochondria have a folded inner membrane."
- While the folded inner membrane (cristae) increases the surface area for reactions, it does not directly support the presence of transport enzymes. Therefore, this option is not relevant to the question.

- **Option 4**: "A contractile protein capable of utilizing ATP is obtained from mitochondria."
- This option refers to contractile proteins and their utilization of ATP. While ATP is produced by mitochondria, this does not specifically relate to transport enzymes, making this option incorrect.

3. **Conclusion**:
- Based on the analysis, **Option 2** is the observation that most strongly supports the view that mitochondria contain transport enzymes aggregated into compact associations.

### Final Answer:
**Option 2**: Disruption of the mitochondria leads to membrane fragments that are able to synthesize ATP.
