Which of the following would be expected to contain the most peroxisomes ?

Options

A. Heart
B. Stomach
C. Liver
D. Pancreas

Answer

**Step-by-Step Solution:**

1. **Understand the Function of Peroxisomes:**
- Peroxisomes are single-membrane-bound organelles found in both plant and animal cells. They contain enzymes that are crucial for various metabolic reactions, particularly those involved in the breakdown of fatty acids and detoxification processes.

2. **Identify the Organs Mentioned:**
- The question provides four options: liver, heart, stomach, and pancreas. We need to analyze which of these organs is metabolically the most active and would therefore contain the most peroxisomes.

3. **Analyze the Metabolic Activity of Each Organ:**
- **Liver:** The liver is known for its high metabolic activity. It plays a central role in carbohydrate metabolism, detoxification, and the metabolism of fats and proteins. This high level of metabolic activity suggests a greater need for peroxisomes.
- **Heart:** While the heart is metabolically active, its primary function is to pump blood, and it does not require as many peroxisomes as the liver.
- **Stomach:** The stomach's primary function is digestion, which does not involve a high concentration of peroxisomes.
- **Pancreas:** The pancreas is involved in digestion and hormone production, but again, it does not have the same metabolic demands as the liver.

4. **Conclusion:**
- Based on the analysis, the liver is expected to contain the most peroxisomes due to its extensive metabolic functions. Therefore, the correct answer is the liver.

**Final Answer:** The liver would be expected to contain the most peroxisomes.
