Peroxisomes have

Options

A. Ribosome
B. DNA
C. Catalase enzyme
D. Centrosome

Answer

### Step-by-Step Solution:

1. **Understanding Peroxisomes**:
- Peroxisomes are small, membrane-bound organelles found in eukaryotic cells. They play a crucial role in various metabolic processes.

2. **Identifying Components of Peroxisomes**:
- The question lists four options: ribosome, DNA, catalase enzyme, and centrosome. We need to determine which of these are present in peroxisomes.

3. **Analyzing Each Option**:
- **Ribosome**: Ribosomes are the sites of protein synthesis and are not found within peroxisomes.
- **DNA**: Peroxisomes do not contain their own DNA. Unlike mitochondria, which have their own DNA, peroxisomes rely on the nuclear DNA of the cell for their protein synthesis.
- **Catalase Enzyme**: Peroxisomes contain catalase, an enzyme that helps break down hydrogen peroxide (H2O2), a toxic byproduct of various metabolic reactions, into water and oxygen.
- **Centrosome**: Centrosomes are involved in cell division and are not found in peroxisomes.

4. **Conclusion**:
- Based on the analysis, the only component that peroxisomes have from the given options is the **catalase enzyme**. Therefore, the correct answer is the third option.
