Peroxysomes contain :-

Options

A. Hydrolytic enzyme
B. Transferase
C. Isomerase
D. Oxidising enzyme (Oxidase)

Answer

**Step-by-Step Solution:**

1. **Understand what peroxisomes are**: Peroxisomes are small, membrane-bound organelles found in the cells of many organisms, particularly in plants. They are involved in various metabolic processes, including the breakdown of fatty acids and the detoxification of harmful substances.

2. **Identify the types of enzymes**: The question lists several types of enzymes: hydrolytic enzymes, transferases, isomerases, oxidizing enzymes, and oxidases. It is important to know what each type of enzyme does:
- **Hydrolytic enzymes**: These enzymes break down compounds by adding water (hydrolysis). They are primarily found in lysosomes.
- **Transferases**: These enzymes transfer functional groups from one molecule to another.
- **Isomerases**: These enzymes rearrange the structure of a molecule without changing its molecular formula.
- **Oxidizing enzymes**: These enzymes facilitate oxidation reactions, which involve the removal of electrons or hydrogen ions from substrates.
- **Oxidases**: A specific type of oxidizing enzyme that catalyzes the transfer of electrons from a substrate to oxygen.

3. **Determine the correct enzyme type present in peroxisomes**: Peroxisomes are known to contain oxidizing enzymes, which are involved in oxidative reactions. They play a crucial role in the metabolism of fatty acids and the detoxification of hydrogen peroxide into water and oxygen.

4. **Eliminate the incorrect options**:
- Hydrolytic enzymes are not present in peroxisomes; they are found in lysosomes.
- Transferases and isomerases are not typically associated with peroxisomes either.
- The main function of peroxisomes is related to oxidation, confirming that the correct answer is oxidizing enzymes.

5. **Conclude the answer**: Based on the functions and characteristics of peroxisomes, the correct answer is that peroxisomes contain oxidizing enzymes.

**Final Answer**: Peroxisomes contain oxidizing enzymes.
