Which cell organelle is not correctly associated with an appropriate enzyme or protein?

Options

A. Mitochondria-cytochrome c
B. Rough endoplasmic reticulum-ribosomes
C. Peroxisomes-catalase
D. Nuclear membrane-amino acid permease

Explanation

To determine which cell organelle is not correctly associated with an appropriate enzyme or protein, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- Mitochondria, Cytochrome C
- Rough Endoplasmic Reticulum, Ribosomes
- Peroxisomes, Catalase
- Nuclear Membrane, Amino Acid Permease

2. **Analyze Mitochondria and Cytochrome C**:
- Mitochondria are known as the powerhouse of the cell and are involved in ATP synthesis.
- Cytochrome C is a protein found in the mitochondria that plays a key role in the electron transport chain.
- **Conclusion**: This association is correct.

3. **Analyze Rough Endoplasmic Reticulum and Ribosomes**:
- The Rough Endoplasmic Reticulum (RER) is studded with ribosomes and is the site of protein synthesis.
- Ribosomes are the molecular machines that translate mRNA into proteins.
- **Conclusion**: This association is also correct.

4. **Analyze Peroxisomes and Catalase**:
- Peroxisomes are organelles that contain enzymes for various metabolic processes, including the breakdown of fatty acids and the detoxification of hydrogen peroxide.
- Catalase is an enzyme found in peroxisomes that catalyzes the decomposition of hydrogen peroxide into water and oxygen.
- **Conclusion**: This association is correct as well.

5. **Analyze Nuclear Membrane and Amino Acid Permease**:
- The nuclear membrane encloses the nucleus and regulates the passage of substances in and out of the nucleus.
- Amino Acid Permease is a protein that facilitates the transport of amino acids across the cell membrane (plasma membrane), not the nuclear membrane.
- **Conclusion**: This association is incorrect.

6. **Final Answer**: The cell organelle that is not correctly associated with an appropriate enzyme or protein is **Nuclear Membrane and Amino Acid Permease**.

### Summary:
The correct answer to the question is **Nuclear Membrane and Amino Acid Permease** because amino acid permease is associated with the plasma membrane, not the nuclear membrane.
