The organelle associated with aerobic respiration is

Options

A. nucleus
B. centriole
C. chloroplast
D. mitochondria

Answer

**Step-by-Step Text Solution:**

1. **Understanding Aerobic Respiration**: Aerobic respiration is a biological process that requires oxygen to convert glucose into energy. This process occurs in various organelles within the cell.

2. **Identifying the Organelles**: The question asks for the organelle specifically associated with aerobic respiration. The options provided are:
- A. Nucleus
- B. Centriole
- C. Chloroplast
- D. Mitochondria

3. **Analyzing Each Option**:
- **Nucleus**: The nucleus is the control center of the cell, housing genetic material and regulating cell activities, but it is not directly involved in aerobic respiration.
- **Centriole**: Centrioles are involved in cell division, specifically in the formation of spindle fibers, and do not play a role in aerobic respiration.
- **Chloroplast**: Chloroplasts are involved in photosynthesis, converting light energy into chemical energy in the form of glucose, but they do not participate in aerobic respiration.
- **Mitochondria**: Mitochondria are known as the "powerhouse of the cell." They are the site where aerobic respiration occurs, utilizing oxygen to oxidize nutrients and produce ATP (adenosine triphosphate), the energy currency of the cell.

4. **Conclusion**: Based on the analysis, the organelle associated with aerobic respiration is **D. Mitochondria**.
