Major mineral constituent of cell membrane is

Options

A. Calcium
B. Phosphorus
C. Sulphur
D. Nitrogen

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the major mineral constituent of the cell membrane from the given options.

2. **List the Options**: The options provided are:
- A) Calcium
- B) Phosphorus
- C) Sulfur
- D) Nitrogen

3. **Analyze Each Option**:
- **Calcium**: While calcium plays a role in cellular functions, it is not a primary component of cell membranes.
- **Phosphorus**: Phosphorus is a key component of phospholipids, which make up the cell membrane. It is also involved in energy transfer (ATP) and is essential for nucleic acids and proteins.
- **Sulfur**: Sulfur is important for certain amino acids and proteins but is not a major component of cell membranes.
- **Nitrogen**: Nitrogen is a component of amino acids and nucleic acids but is not a direct constituent of cell membranes.

4. **Conclusion**: Based on the analysis, phosphorus is identified as the major mineral constituent of the cell membrane.

5. **Final Answer**: The correct answer is **B) Phosphorus**.
