Food is converted to energy in

Options

A. Chloroplast
B. Nucleus
C. Mitochondria
D. None of the above.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks where food is converted into energy within a cell.

2. **Identifying the Process**: The conversion of food into energy is known as cellular respiration. This is a crucial biological process that occurs in living organisms.

3. **Locating the Site of Cellular Respiration**: Cellular respiration primarily takes place in a specific organelle within the cell.

4. **Identifying the Organelle**: The correct organelle where cellular respiration occurs is the mitochondria.

5. **Understanding the Role of Mitochondria**: Mitochondria are often referred to as the "powerhouse of the cell" because they are responsible for producing energy.

6. **Energy Production**: During cellular respiration, food is converted into energy in the form of ATP (adenosine triphosphate), which is known as the energy currency of the cell.

7. **Conclusion**: Therefore, the answer to the question is that food is converted to energy in the mitochondria.

### Final Answer:
Food is converted to energy in the mitochondria.
