Lysosome containing inactive enzymes is

Options

A. Primary lysosome
B. Autophagic vacuole
C. Residual body
D. Secondary lysosome

Answer

To solve the question "Lysosome containing inactive enzymes is," we will analyze the options provided and determine which one correctly describes the lysosome in question.

### Step-by-Step Solution:

1. **Understanding Lysosomes**:
- Lysosomes are membrane-bound organelles that contain digestive enzymes. These enzymes are responsible for breaking down waste materials and cellular debris.

2. **Identifying the Type of Lysosome**:
- Lysosomes can contain inactive enzymes when they are newly formed. These are often referred to as primary lysosomes. They become active when they fuse with other vesicles containing materials to be digested.

3. **Analyzing the Options**:
- **Option 1: Autosome**: This term is not commonly used in the context of lysosomes. The correct term for lysosomes that contain inactive enzymes is primary lysosomes.
- **Option 2: Autophagic Vacuole**: This option is incorrect because autophagic vacuoles are involved in the degradation of cellular components and contain active enzymes.
- **Option 3: Residual Body**: This option is also incorrect. Residual bodies are formed from the remnants of lysosomes after digestion and contain indigestible material.

4. **Conclusion**:
- The correct answer is that lysosomes containing inactive enzymes are referred to as **primary lysosomes**.

### Final Answer:
Lysosome containing inactive enzymes is a **primary lysosome**.
