`beta`-oxidation takes place in

Options

A. Matrix of mitochondria
B. Cell cytoplasm
C. Inter mitochondrial chamber
D. Ribosomes

Answer

**Step-by-Step Solution:**

1. **Understanding Beta-Oxidation**:
- Beta-oxidation is a catabolic process that involves the breakdown of fatty acids. During this process, fatty acids are converted into acetyl coenzyme A (acetyl-CoA).

2. **Location of Beta-Oxidation**:
- In eukaryotic cells, beta-oxidation occurs in the mitochondrial matrix. This is the innermost compartment of the mitochondria where various metabolic processes take place.

3. **Comparison with Prokaryotes**:
- In prokaryotic cells, which lack mitochondria, beta-oxidation occurs in the cytosol. However, since the question specifically asks about eukaryotes, we focus on the mitochondrial matrix.

4. **Conclusion**:
- Therefore, the answer to the question "Beta-oxidation takes place in" is the mitochondrial matrix in eukaryotic cells.

**Final Answer**: Beta-oxidation takes place in the mitochondrial matrix in eukaryotes.
