Options

A. K, Ca and Mg
B. P, Ca only
C. N, P, K and Ca
D. N, P, K, B and Mn

Answer

To answer the question about the elements mainly involved in cell membrane synthesis and normal functioning of the cell membrane, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Cell Membrane Composition**:
- The cell membrane is primarily composed of phospholipids, proteins, cholesterol, and carbohydrates. The synthesis and maintenance of these components require various elements.

2. **Identifying Key Elements**:
- The main elements involved in the synthesis and functioning of the cell membrane include:
- **Phosphorus (P)**: Essential for the formation of phospholipids, which are the building blocks of the cell membrane.
- **Nitrogen (N)**: Important for the synthesis of amino acids and nucleotides, which are crucial for protein and nucleic acid formation.
- **Potassium (K)**: Plays a critical role in maintaining membrane potential and cell signaling.
- **Calcium (Ca)**: Involved in various cellular processes and helps in stabilizing membrane structure.

3. **Reviewing the Options**:
- Based on the elements identified, we can review the options provided in the question:
- Option 1: Potassium, Calcium, Magnesium
- Option 2: Nitrogen, Phosphorus, Potassium
- Option 3: Nitrogen, Potassium, Boron, Manganese

4. **Selecting the Correct Option**:
- From the analysis, the correct option that includes the elements primarily involved in cell membrane synthesis and functioning is:
- **Option 2: Nitrogen, Phosphorus, Potassium**

### Final Answer:
The elements mainly involved in cell membrane synthesis and normal functioning of the cell membrane are **Nitrogen, Phosphorus, and Potassium**.
