Which of the following prevents the rupturing of lysosomal membrane :

Options

A. Cholesterol
B. Vit. A
C. Testosterone
D. UV - rays

Answer

To solve the question "Which of the following prevents the rupturing of lysosomal membrane?" we can follow these steps:

### Step 1: Understand the Function of Lysosomes
Lysosomes are membrane-bound organelles found in cells that contain digestive enzymes. Their primary function is to break down waste materials and cellular debris. They also digest pathogens that enter the cell, making them crucial for cellular health.

**Hint:** Remember that lysosomes act as the cell's waste disposal system and are involved in digestion.

### Step 2: Identify the Importance of the Lysosomal Membrane
The lysosomal membrane is essential because it contains the enzymes that break down materials. If the membrane ruptures, these enzymes can leak out and start digesting the cell itself, leading to cell death. Therefore, maintaining the integrity of the lysosomal membrane is vital for cell survival.

**Hint:** Think about what would happen if the protective membrane of lysosomes were to break.

### Step 3: Evaluate the Options
The options provided are:
- Cholesterol
- Vitamin A
- Testosterone
- UV rays

We need to determine which of these options helps prevent the rupture of the lysosomal membrane.

**Hint:** Consider the role of each option in cellular health and membrane stability.

### Step 4: Analyze Each Option
- **Cholesterol:** Cholesterol is a component of cell membranes and helps maintain membrane stability and fluidity. It is known to play a protective role in preventing the rupture of lysosomal membranes.

- **Vitamin A:** While important for various bodily functions, it does not play a direct role in stabilizing lysosomal membranes.

- **Testosterone:** This hormone is involved in various physiological functions but does not contribute to the stability of lysosomal membranes.

- **UV Rays:** Ultraviolet rays can cause damage to cells and their components, including membranes, leading to increased chances of rupture.

**Hint:** Focus on the role of cholesterol in maintaining membrane integrity.

### Step 5: Conclusion
Based on the analysis, cholesterol is the correct answer as it prevents the rupturing of the lysosomal membrane.

**Final Answer:** Cholesterol prevents the rupturing of lysosomal membrane.
