Choose the incorrect match.

Options

A. Nucleus - RNA synthesis
B. Lysosome - Protein synthesis
C. Mitochondria - Respiration
D. Cytoskeleton - Microtubules

Answer

To solve the question "Choose the incorrect match," we need to evaluate each of the given options and determine which one does not correctly associate the cellular structure with its function.

### Step-by-Step Solution:

1. **Identify the Options**:
- Option 1: Nucleus and RNA synthesis
- Option 2: Lysosome and protein synthesis
- Option 3: Mitochondria and respiration
- Option 4: Cytoskeleton and microtubules

2. **Analyze Option 1: Nucleus and RNA Synthesis**:
- The nucleus is indeed the site of RNA synthesis as it contains the genetic material (DNA) and is responsible for transcription, where RNA is synthesized.
- **Conclusion**: This option is correct.

3. **Analyze Option 2: Lysosome and Protein Synthesis**:
- Lysosomes are membrane-bound organelles that contain digestive enzymes. Their primary function is to break down waste materials and cellular debris, not to synthesize proteins.
- **Conclusion**: This option is incorrect.

4. **Analyze Option 3: Mitochondria and Respiration**:
- Mitochondria are known as the powerhouse of the cell and are responsible for cellular respiration, where ATP is produced from glucose and other substrates.
- **Conclusion**: This option is correct.

5. **Analyze Option 4: Cytoskeleton and Microtubules**:
- The cytoskeleton provides structural support and is composed of microtubules, microfilaments, and intermediate filaments. Microtubules are a key component of the cytoskeleton.
- **Conclusion**: This option is correct.

6. **Final Conclusion**:
- The incorrect match is **Option 2: Lysosome and Protein Synthesis**.

### Summary:
The incorrect match among the given options is Option 2: Lysosome and Protein Synthesis.
