The common component of membrane of organelles like mitochondria, endoplasmic reticulum and nucleus is

Options

A. glycolipid
B. glycoprotein
C. nucleoprotein
D. lipoprotein

Explanation

To solve the question regarding the common component of the membrane of organelles like mitochondria, endoplasmic reticulum, and nucleus, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organelles**: The question mentions three organelles: mitochondria, endoplasmic reticulum (ER), and nucleus. All these organelles are found in eukaryotic cells.

2. **Understand the Function of Each Organelle**:
- **Mitochondria**: Known as the powerhouse of the cell, responsible for ATP production.
- **Endoplasmic Reticulum**: Involved in the synthesis of proteins (rough ER) and lipids (smooth ER).
- **Nucleus**: Contains the cell's genetic material (DNA).

3. **Consider the Membrane Composition**: Each of these organelles is surrounded by a membrane. The question asks for a common component of these membranes.

4. **Evaluate the Options**: The options provided are:
- Glycolipid
- Glycoprotein
- Nucleoprotein
- Lipoprotein

5. **Analyze Each Option**:
- **Glycolipid**: Composed of carbohydrates and lipids; not a major component of all organelle membranes.
- **Glycoprotein**: Composed of carbohydrates and proteins; also not a common component across all mentioned organelles.
- **Nucleoprotein**: Specifically related to the nucleus; not found in mitochondria or ER.
- **Lipoprotein**: Composed of lipids and proteins; is a major component of cell membranes, including those of mitochondria, ER, and nucleus.

6. **Conclusion**: The common component of the membranes of mitochondria, endoplasmic reticulum, and nucleus is **Lipoprotein**.

### Final Answer:
The common component of the membrane of organelles like mitochondria, endoplasmic reticulum, and nucleus is **Lipoprotein**.
