Mitochondrial matrix possesses

Options

A. Enzymes of Krebs cycle and protein synthesis
B. Formation of Leucocytes
C. Enzyme of Calvin cycle
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding Mitochondrial Matrix**: The mitochondrial matrix is the innermost compartment of the mitochondria, surrounded by the inner membrane. It is crucial for various metabolic processes.

2. **Identifying Components of Mitochondrial Matrix**: The matrix contains enzymes that play a significant role in cellular respiration, particularly in the Krebs cycle (also known as the citric acid cycle or TCA cycle).

3. **Enzymes of the Krebs Cycle**: The Krebs cycle involves a series of enzymatic reactions that convert acetyl-CoA into carbon dioxide and energy-rich molecules like NADH and FADH2. These enzymes are soluble and located in the mitochondrial matrix.

4. **Ribosomes and Protein Synthesis**: The mitochondrial matrix also contains its own ribosomes, which are involved in the synthesis of some proteins that are essential for mitochondrial function.

5. **Exclusion of Incorrect Options**:
- **Formation of Leukocytes**: This process occurs in the bone marrow, not in the mitochondrial matrix, making this option incorrect.
- **Enzymes of the Calvin Cycle**: The Calvin cycle is part of photosynthesis in plants and occurs in the chloroplasts, not in mitochondria, thus this option is also incorrect.
- **Anoptes**: This term does not relate to the functions of the mitochondrial matrix and is incorrect.

6. **Conclusion**: The correct answer is that the mitochondrial matrix possesses enzymes of the Krebs cycle and components necessary for protein synthesis.

**Final Answer**: The mitochondrial matrix possesses enzymes of the Krebs cycle and is involved in protein synthesis.
