Cellular respiration is carried out by

Options

A. ribosome
B. mitochondria
C. chloroplast
D. golgi bodies

Answer

**Step-by-Step Solution:**

1. **Understanding Cellular Respiration**: Cellular respiration is a biochemical process where complex organic molecules, primarily carbohydrates, fats, and proteins, are broken down to release energy. This process is essential for the survival of cells as it provides the energy needed for various cellular activities.

2. **Identifying the Key Organelles**: The question lists several organelles: ribosomes, mitochondria, chloroplasts, and Golgi bodies. We need to determine which of these organelles is primarily responsible for cellular respiration.

3. **Role of Mitochondria**: Among the listed organelles, mitochondria are known as the "powerhouse of the cell." This is because they are the primary site for aerobic respiration, where the breakdown of complex molecules occurs, leading to the production of ATP (adenosine triphosphate), the energy currency of the cell.

4. **Other Organelles**:
- **Ribosomes**: These are involved in protein synthesis, not respiration.
- **Chloroplasts**: These organelles are responsible for photosynthesis, which is a different process from cellular respiration.
- **Golgi Bodies**: Their main function is packaging and transporting proteins and lipids, not respiration.

5. **Conclusion**: Based on the functions of the organelles listed, the correct answer to the question "Cellular respiration is carried out by" is **mitochondria**.

**Final Answer**: Cellular respiration is carried out by **mitochondria**.
