The perosisomes are associated with the phenomenon of :-

Options

A. Oxidative anabolism
B. De-gradation of `H_(2)O`
C. Anaerobic respiration
D. Photorespiration and degradation of `H_(2)O_(2)`

Answer

**Step-by-Step Solution:**

1. **Understanding Peroxisomes**: Peroxisomes are membrane-bound organelles found in eukaryotic cells. They play a crucial role in the oxidation of specific biomolecules.

2. **Function of Peroxisomes**: These organelles contain enzymes that oxidize certain molecules, such as fatty acids and amino acids. This process of oxidation leads to the production of hydrogen peroxide.

3. **Toxicity of Hydrogen Peroxide**: Hydrogen peroxide is a potentially toxic byproduct of the oxidation reactions occurring in peroxisomes. It can react with many other molecules, which can be harmful to the cell.

4. **Neutralization of Hydrogen Peroxide**: To mitigate the toxicity of hydrogen peroxide, peroxisomes contain enzymes like catalase. Catalase converts hydrogen peroxide into water and oxygen, thus neutralizing its harmful effects.

5. **Evaluating the Options**:
- **Oxidative Anabolism**: This refers to the synthesis of complex molecules from simpler ones. Peroxisomes are involved in oxidative metabolism, not anabolism, so this option is incorrect.
- **Degradation of Water**: Water is not degraded in peroxisomes; rather, it is produced. Therefore, this option is also incorrect.
- **Anaerobic Respiration**: Peroxisomes do not participate in respiration, making this option incorrect as well.
- **Photorespiration and Degradation of Hydrogen Peroxide**: This option is correct because peroxisomes are indeed involved in the degradation of hydrogen peroxide.

6. **Conclusion**: The correct answer is that peroxisomes are associated with the degradation of hydrogen peroxide.

**Final Answer**: The peroxisomes are associated with the phenomenon of degradation of hydrogen peroxide.
