Inner membrane of mitochondrion possesses

Options

A. `F_(0)-F_(1)` particles
B. ATP-ase
C. TCA enzyme
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Mitochondria Structure**:
- Mitochondria are known as the powerhouse of the cell and are characterized by a double membrane structure, consisting of an outer membrane and an inner membrane.

2. **Identifying Components of the Inner Membrane**:
- The inner membrane of mitochondria contains several important components. These include:
- F0-F1 particles (ATP synthase)
- ATPase
- Enzymes of the TCA (tricarboxylic acid) cycle

3. **F0-F1 Particles**:
- F0-F1 particles are located in the inner mitochondrial membrane and are crucial for ATP production. They are associated with the cristae (the folds of the inner membrane) and play a role in oxidative phosphorylation.

4. **ATPase**:
- ATPase is an enzyme that is also embedded in the inner mitochondrial membrane. It facilitates the synthesis of ATP, which is the energy currency of the cell.

5. **TCA Cycle Enzymes**:
- The enzymes of the TCA cycle, such as succinate dehydrogenase and isocitrate dehydrogenase, are located in the inner mitochondrial membrane. These enzymes are essential for cellular respiration and energy production.

6. **Conclusion**:
- Since all the mentioned components (F0-F1 particles, ATPase, and TCA cycle enzymes) are present in the inner membrane of mitochondria, the correct answer to the question is "all of the above."

**Final Answer**: All of the above.
