The membrane of rough endoplasmic reticulum has power of bind ribosome because it contains

Options

A. Ribophorin
B. Glycolipid
C. Glycoprotein
D. Both (1) and (3)

Answer

**Step-by-Step Solution:**

1. **Understanding the Rough Endoplasmic Reticulum (RER):**
- The rough endoplasmic reticulum is a type of endoplasmic reticulum that is studded with ribosomes on its cytoplasmic surface, giving it a "rough" appearance. This structure is crucial for its function in protein synthesis.

2. **Identifying the Binding Mechanism:**
- The question asks why the membrane of the rough endoplasmic reticulum has the ability to bind ribosomes. The key to this lies in specific proteins present in the membrane.

3. **Role of Riboflurin:**
- The correct answer is that the rough endoplasmic reticulum contains ribosome receptor proteins, specifically a type known as Riboflurin. These proteins facilitate the binding of the ribosomal 60S subunit to the rough endoplasmic reticulum.

4. **Exclusion of Other Options:**
- The other options provided (glycolipids and glycoproteins) do not play a direct role in the binding of ribosomes to the rough endoplasmic reticulum.
- Glycolipids are important for cell membrane structure and signaling but do not bind ribosomes.
- Glycoproteins are proteins with carbohydrate chains but are not specifically responsible for ribosome binding.

5. **Conclusion:**
- Therefore, the rough endoplasmic reticulum can bind ribosomes due to the presence of ribosome receptor proteins, such as Riboflurin.

**Final Answer:**
The membrane of rough endoplasmic reticulum has the power to bind ribosomes because it contains Riboflurin.
