In which of the following parts of mitochondria, succinic dehydrogenase enzyme is located
" " Or
In mitochondria, enzyme cytochrome oxidase is present in

Options

A. Perimitochondrial space
B. Outer membrane
C. Inner membrane
D. Matrix

Answer

To answer the question regarding the location of succinic dehydrogenase and cytochrome oxidase in the mitochondria, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Mitochondria**:
- Mitochondria have several distinct parts: the outer membrane, inner membrane, intermembrane space (or perimitochondrial space), and the matrix. Each of these parts has specific functions and contains different enzymes.

2. **Identify the Location of Succinic Dehydrogenase**:
- Succinic dehydrogenase is an enzyme involved in the citric acid cycle (Krebs cycle) and is known to be located in the inner membrane of the mitochondria.

3. **Identify the Location of Cytochrome Oxidase**:
- Cytochrome oxidase is part of the electron transport chain and is also located in the inner membrane of the mitochondria. It plays a crucial role in the final steps of cellular respiration.

4. **Conclusion**:
- Both succinic dehydrogenase and cytochrome oxidase are present in the inner membrane of the mitochondria. Therefore, the correct answer to the question is the inner membrane.

### Final Answer:
The succinic dehydrogenase enzyme is located in the inner membrane of mitochondria, and cytochrome oxidase is also present in the inner membrane.
