The cell organelle that is involved in protein synthesis is continuous with

Options

A. Inner membrane of nucleus
B. outer membrane of nucleus
C. Outer mitochondrial membrane
D. Inner mitochondria membrane

Answer

To answer the question, "The cell organelle that is involved in protein synthesis is continuous with," we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Organelle Involved in Protein Synthesis**:
- The primary organelle responsible for protein synthesis is the **Endoplasmic Reticulum (ER)**.

2. **Differentiate Between Types of Endoplasmic Reticulum**:
- The Endoplasmic Reticulum has two types:
- **Rough Endoplasmic Reticulum (RER)**: This type is studded with ribosomes, which are the sites of protein synthesis.
- **Smooth Endoplasmic Reticulum (SER)**: This type does not have ribosomes and is primarily involved in lipid synthesis.

3. **Establish the Relationship with the Nucleus**:
- The Rough Endoplasmic Reticulum is continuous with the **outer membrane of the nucleus**. The nucleus itself is a double-membrane-bound organelle that contains genetic material (DNA).

4. **Conclusion**:
- Therefore, the cell organelle involved in protein synthesis (Rough Endoplasmic Reticulum) is continuous with the **outer membrane of the nucleus**.

### Final Answer:
The cell organelle that is involved in protein synthesis is continuous with the **outer membrane of the nucleus**.
