Assertion : `F_1` particles are present in the inner mitochondrial membrane.
Reason : An electron gradient formed on the inner mitochondrial membrane, forms ATP.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reson are false.

Explanation

To solve the question, we need to evaluate the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that `F_1` particles are present in the inner mitochondrial membrane.

- **Explanation**: The F1 particles are indeed part of ATP synthase, which is located in the inner mitochondrial membrane. They play a crucial role in ATP production during cellular respiration.

### Step 2: Analyze the Reason
The reason provided is that an electron gradient formed on the inner mitochondrial membrane forms ATP.

- **Explanation**: The statement is misleading. While it is true that a proton gradient (not an electron gradient) across the inner mitochondrial membrane is essential for ATP synthesis, it is the flow of protons through ATP synthase that drives the conversion of ADP and inorganic phosphate into ATP. The electron transport chain creates the proton gradient, but the reason as stated does not accurately reflect this process.

### Step 3: Conclusion
Based on the analysis:
- The assertion is **True**.
- The reason is **False**.

Thus, the correct answer is that the assertion is true, but the reason is false.

### Final Answer
Assertion: True
Reason: False
Correct Option: C
