Which one of the following is not correct pairing of the structure with function?

Options

A. Golgi complex-breakdown of complex molecules
B. Mitochondrion-production of ATP
C. Ribosomes-site of protein synthesis
D. Chloroplasts-photosynthesis

Explanation

To determine which pairing of structure with function is incorrect, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Structures and Their Functions**: We need to look at the structures mentioned in the options and their corresponding functions.

2. **Analyze the First Option - Golgi Complex**:
- **Structure**: Golgi Complex (or Golgi Apparatus)
- **Function**: The Golgi complex is primarily involved in processing and packaging proteins and lipids.
- **Incorrect Pairing**: The option states that the Golgi complex is responsible for the breakdown of complex molecules, which is incorrect. The Golgi complex does not break down molecules; it modifies, sorts, and packages them.

3. **Analyze the Second Option - Mitochondria**:
- **Structure**: Mitochondria
- **Function**: Mitochondria are known as the powerhouse of the cell and are responsible for the production of ATP (adenosine triphosphate), which is the energy currency of the cell.
- **Correct Pairing**: This is a correct pairing.

4. **Analyze the Third Option - Ribosomes**:
- **Structure**: Ribosomes
- **Function**: Ribosomes are the sites of protein synthesis in the cell.
- **Correct Pairing**: This is also a correct pairing.

5. **Analyze the Fourth Option - Chloroplasts**:
- **Structure**: Chloroplasts
- **Function**: Chloroplasts are involved in photosynthesis, converting light energy into chemical energy.
- **Correct Pairing**: This is a correct pairing as well.

6. **Conclusion**: After analyzing all the options, we find that the only incorrect pairing is the Golgi complex with the breakdown of complex molecules.

### Final Answer:
The incorrect pairing of structure with function is: **Golgi complex - breakdown of complex molecules.**
