Options

A. Integral membrane protein complex acts as a site of ATP synthesis
B. Peripheral membrane protein complex acts as a site of protein synthesis
C. Integral membrane protein complex acts as a site of protein synthesis
D. Complex molecule made up of phospholipids

Answer

To answer the question regarding the F0 part of ATP synthase (Complex V), we will break down the information step by step.

### Step-by-Step Solution:

1. **Understanding ATP Synthase**: ATP synthase is an enzyme complex that synthesizes ATP (adenosine triphosphate) from ADP (adenosine diphosphate) and inorganic phosphate (Pi) using a proton gradient.

2. **Structure of ATP Synthase**: ATP synthase consists of two main components:
- **F1**: This part is located in the mitochondrial matrix and is responsible for the catalytic activity of ATP synthesis.
- **F0**: This part is embedded in the inner mitochondrial membrane and is responsible for the translocation of protons.

3. **Function of F0**: The F0 component acts as a channel for protons to flow back into the mitochondrial matrix. This flow of protons is driven by the proton electrochemical gradient established during the electron transport chain.

4. **ATP Synthesis Mechanism**: As protons flow through the F0 complex, it causes conformational changes that drive the synthesis of ATP from ADP and Pi in the F1 component.

5. **Conclusion**: The F0 part of ATP synthase is an integral membrane protein complex that acts as a site for the movement of protons, which is crucial for ATP synthesis.

### Final Answer:
The F0 part of ATP synthase (Complex V) is an integral membrane protein complex that acts as a site for the movement of protons, facilitating ATP synthesis.
