A cell biologist used ultrasonic method to disrupt the cell and found fragments in cell organelle, which served as site of ATP synthesis. These fragments actually are the parts of

Options

A. mitochondria
B. lysosomes
C. liposomes
D. ribosomes

Answer

To solve the question, we need to identify which cell organelle is responsible for ATP synthesis based on the information provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question states that a cell biologist used an ultrasonic method to disrupt a cell, leading to the discovery of fragments that serve as sites of ATP synthesis.

2. **Identifying the Options**: The options provided are:
- Option 1: Mitochondria
- Option 2: Lysosomes
- Option 3: Liposomes
- Option 4: Ribosomes

3. **Analyzing Each Option**:
- **Option 1: Mitochondria**: Mitochondria are known as the powerhouse of the cell. They are the primary site for ATP synthesis through cellular respiration. This option is likely correct.
- **Option 2: Lysosomes**: Lysosomes are involved in digestion and waste removal within the cell. They do not synthesize ATP, so this option is incorrect.
- **Option 3: Liposomes**: Liposomes are artificial spherical vesicles used for drug delivery and do not play a role in ATP synthesis. Therefore, this option is also incorrect.
- **Option 4: Ribosomes**: Ribosomes are the sites of protein synthesis, not ATP synthesis. Thus, this option is incorrect as well.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 1: Mitochondria**, as they are the organelles responsible for ATP synthesis.

### Final Answer:
The fragments found by the cell biologist are parts of **Mitochondria**.
