The correct Answer is:
To solve the question regarding the composition of the erythrocyte membrane in human beings, we can break it down step by step: ### Step-by-Step Solution: 1. **Understanding Erythrocytes**: Erythrocytes, commonly known as red blood cells (RBCs), have a unique membrane structure that is crucial for their function. 2. **Membrane Composition**: The membrane of erythrocytes is primarily composed of two types of macromolecules: proteins and lipids. 3. **Proportion of Proteins**: Research indicates that the erythrocyte membrane contains a higher proportion of proteins compared to lipids. Specifically, the integral proteins present in the membrane are larger in size and are more abundant. 4. **Quantifying the Components**: - Proteins make up approximately **52%** of the erythrocyte membrane. - Lipids account for about **40%** of the membrane composition. 5. **Final Answer**: Therefore, the membrane of the erythrocyte has approximately **52% proteins** and **40% lipids**. ### Summary of the Answer: In human beings, the membrane of the erythrocyte has approximately **52% proteins** and **40% lipids**. ---
