A : Cytochrome c is the peripheral protein.
R : It is found attached on the perimitochondrial space side of the inner mitochondrial membrane.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion and Reason**: The assertion states that "Cytochrome c is a peripheral protein." The reason given is "It is found attached on the perimitochondrial space side of the inner mitochondrial membrane."

2. **Evaluating the Assertion**: Cytochrome c is indeed classified as a peripheral protein. Peripheral proteins are those that are not embedded within the membrane but are associated with the surface of the membrane. In the case of cytochrome c, it is a mobile electron carrier involved in the electron transport chain (ETS) and is located on the inner mitochondrial membrane.

3. **Evaluating the Reason**: The reason states that cytochrome c is found attached to the perimitochondrial space side of the inner mitochondrial membrane. This is accurate as cytochrome c is located on the outer side of the inner mitochondrial membrane, adjacent to the perimitochondrial space.

4. **Conclusion**: Both the assertion and the reason are true. Furthermore, the reason provides a correct explanation for the assertion. Therefore, we can conclude that both the assertion and reason are correct, and the reason is indeed the correct explanation for the assertion.

5. **Final Answer**: The correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
