Experimental material used for the study ale chemical structure of cell membrane was

Options

A. White blood cells
B. Red blood cells
C. Platelets
D. Lymph cells

Answer

To answer the question regarding the experimental material used for the study of the chemical structure of the cell membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the experimental material that was used to study the chemical structure of the cell membrane.

2. **Identifying Options**: The options provided are:
- A) WBCs (White Blood Cells)
- B) RBCs (Red Blood Cells)
- C) Platelets
- D) Lymph Cells

3. **Analyzing the Options**:
- **WBCs**: While they play a role in the immune system, they are not primarily studied for their cell membrane structure.
- **Platelets**: These are cell fragments involved in clotting and do not provide a comprehensive model for studying cell membranes.
- **Lymph Cells**: These are also part of the immune system and do not serve as a primary model for cell membrane studies.

4. **Choosing the Best Option**:
- **RBCs (Red Blood Cells)**: These cells have been extensively studied for their membrane structure. They are ideal for such studies because they have a simple and well-defined membrane structure that is rich in proteins, lipids, and carbohydrates.

5. **Supporting Evidence**:
- The RBC membrane consists of approximately 52% proteins, 40% lipids, and 10% carbohydrates, along with cholesterol. This composition supports the fluid mosaic model of the cell membrane, which was proposed by Singer and Nicolson.

6. **Conclusion**: Based on the analysis, the best experimental material used for the study of the chemical structure of the cell membrane is **RBCs (Red Blood Cells)**.

### Final Answer:
The experimental material used for the study of the chemical structure of the cell membrane was **RBCs (Red Blood Cells)**.
