Lysosomes are called suicidal bags because they have

Options

A. phagocytic activity
B. hydrolytic enzymes
C. ` beta ` - oxidation enzymes
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding Lysosomes**: Begin by recognizing that lysosomes are membrane-bound organelles found in eukaryotic cells. Their primary function is to break down complex organic molecules.

2. **Function of Lysosomes**: Lysosomes contain enzymes that are crucial for digestion. These enzymes help in the breakdown of various biomolecules, including proteins, polysaccharides, and lipids.

3. **Role of Hydrolytic Enzymes**: The specific enzymes found in lysosomes are known as hydrolytic enzymes or digestive enzymes. These enzymes are responsible for the degradation of worn-out cell components, food particles, and even foreign particles like viruses.

4. **Autolysis**: When lysosomes release their hydrolytic enzymes within the cell, they can digest the cell's own components. This process is known as autolysis, which can lead to cell death. This self-digestion is why lysosomes are often referred to as "suicidal bags."

5. **Evaluating the Options**:
- Option A (Phagocytic activity) refers to the process of engulfing particles, which is not the primary reason for the term "suicidal bags."
- Option B (Hydrolytic enzymes) is the correct answer, as these enzymes enable lysosomes to digest their own cellular components.
- Option C (Beta oxidation enzymes) are found in peroxisomes and are not related to lysosomes.
- Option D (All of these) is incorrect because not all the options are relevant to the definition of "suicidal bags."

6. **Conclusion**: Therefore, the correct answer is **Option B: Hydrolytic enzymes**, as they are the reason lysosomes are called "suicidal bags."
