The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks what products of cellular wear and tear are stored in lysosomes of neurons as we age. 2. **Identifying Key Terms**: - **Lysosomes**: Organelles that contain digestive enzymes to break down waste materials and cellular debris. - **Neurons**: Nerve cells that transmit information throughout the body. - **Wear and Tear**: Refers to the damage that accumulates in cells over time. 3. **Analyzing the Options**: - **Option A: Nizis Granule**: These are structures found in neurons that consist of rough endoplasmic reticulum and ribosomes, but they are not specifically related to the storage of wear and tear products. - **Option B: Mylene**: This refers to the insulating layer around neurons, not related to lysosomal storage. - **Option C: Lipoprotein**: These are involved in transporting lipids in the body, not specifically related to lysosomal storage of cellular debris. - **Option D: Lipo-Fission Granules**: These are yellow-brown pigments composed of lipids that contain the residues of lysosomal digestion and are considered aging or wear and tear pigments. 4. **Conclusion**: The correct answer is **Lipo-Fission Granules** (Option D) as they are specifically associated with the storage of products from cellular wear and tear in the lysosomes of neurons. ### Final Answer: The products of cellular wear and tear are stored in lysosomes of neurons as **Lipo-Fission Granules**. ---
