Options

A. Quantasomes
B. `CF_(0)-CF_(1)`
C. Photosystems
D. Pyrenoids

Answer

To answer the question "Particles of thylakoid membranes involved in ATP synthesis is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Thylakoid Structure**:
- Thylakoids are membrane-bound structures within chloroplasts that are essential for photosynthesis. They contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

2. **Identifying the Function of Thylakoids**:
- The primary function of thylakoids is to facilitate the light reactions of photosynthesis, where light energy is converted into chemical energy in the form of ATP and NADPH.

3. **Recognizing Key Components**:
- Within the thylakoid membranes, there are several important components, including photosystems (PSI and PSII), cytochrome complexes, and ATP synthase.

4. **Focusing on ATP Synthesis**:
- ATP synthesis occurs through a process called photophosphorylation, which is driven by a proton gradient created by the electron transport chain in the thylakoid membranes.

5. **Identifying the Correct Particles**:
- The particles specifically responsible for ATP synthesis in the thylakoid membranes are the ATP synthase complexes, which are often referred to as CF0-CF1 ATP synthase.

6. **Conclusion**:
- Based on the information, the correct answer to the question is **CF0-CF1** (option 2), as it is the complex involved in ATP synthesis within the thylakoid membranes.

### Final Answer:
The particles of thylakoid membranes involved in ATP synthesis are **CF0-CF1**.
