Cells involved in energy consumption have a large number of a

Options

A. Ribosome
B. Mitochondria
C. Peroxisomes
D. Lysosome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which organelle is present in large numbers in cells that are heavily involved in energy consumption.

2. **Analyzing the Options**:
- **Ribosomes**: These are responsible for protein synthesis, not primarily for energy consumption.
- **Mitochondria**: Known as the powerhouse of the cell, they are crucial for energy production through ATP synthesis.
- **Peroxisomes**: These organelles are involved in oxidative reactions and detoxification, not directly in energy production.
- **Lysosomes**: These are digestive organelles that break down macromolecules and waste, but they do not play a direct role in energy production.

3. **Identifying the Correct Answer**: Given that mitochondria are responsible for producing ATP, which is the energy currency of the cell, cells that consume more energy (like muscle and heart cells) will have a higher number of mitochondria.

4. **Conclusion**: Therefore, the correct answer to the question is **mitochondria**.
