Under what conditions do lysosomes cause autolysis

Options

A. Starvation
B. Excess food
C. Injection
D. Respiration

Answer

### Step-by-Step Solution:

1. **Understanding Autolysis**: Autolysis refers to the process where a cell self-digests its own components. This is often facilitated by lysosomes, which contain digestive enzymes.

2. **Identifying Conditions for Autolysis**: The question asks under what conditions lysosomes cause autolysis. We need to evaluate different scenarios that might trigger this process.

3. **Evaluating Options**:
- **Option 1: Starvation**: In this condition, cells lack nutrients. To survive, lysosomes initiate autolysis by releasing digestive enzymes to break down cellular components for energy. This is the correct answer.
- **Option 2: Excess Food**: This condition does not trigger autolysis, as the cell has sufficient nutrients and energy. Therefore, this option is incorrect.
- **Option 3: Injection**: This option is vague and does not relate to the internal cellular processes that lead to autolysis. Thus, it is incorrect.
- **Option 4: Respiration**: Respiration is a process that generates energy and does not lead to autolysis. Hence, this option is also incorrect.

4. **Conclusion**: The only condition that leads to autolysis by lysosomes is starvation, where the cell resorts to digesting its own components for survival.

### Final Answer:
The correct condition under which lysosomes cause autolysis is **starvation**.
