which part of a cell carries out respiration ?

Options

A. Endoplasmic reticulum
B. Golgi bodies
C. Nucleus
D. Mitochondria

Answer

**Step-by-Step Solution:**

1. **Understanding Respiration**: Respiration is a biochemical process that occurs in cells to convert food into energy. This energy is stored in the form of ATP (adenosine triphosphate), which is essential for various cellular functions.

2. **Identifying Cell Organelles**: The question provides four options: endoplasmic reticulum, Golgi bodies, nucleus, and mitochondria. Each of these organelles has specific functions within the cell.

3. **Analyzing Each Option**:
- **Endoplasmic Reticulum**: This organelle is primarily involved in the synthesis of proteins and lipids, not respiration.
- **Golgi Bodies**: These are responsible for packaging and distributing proteins and lipids but do not play a role in respiration.
- **Nucleus**: Known as the brain of the cell, it regulates cell functions and contains genetic material, but it does not carry out respiration.
- **Mitochondria**: This organelle is specifically known for its role in energy production through the process of respiration. It breaks down food molecules to produce ATP.

4. **Conclusion**: Based on the analysis, the correct answer to the question "which part of a cell carries out respiration?" is the mitochondria. This organelle is often referred to as the "Power House of the Cell" because it is where energy synthesis occurs.

5. **Final Answer**: The part of a cell that carries out respiration is the **mitochondria**.
