In the plasma membrane, lipid helps in:
Correct answer: D. All of these
- A. Flexibility
- B. Chemical climate
- C. Transfer of molecules
- D. All of these
Explanation
In the plasma membrane, the lipids help in the transport of molecules, because the lipid-soluble non-polar substances can easily diffuse through them. Since many non-polar substances are chemicals, the lipid bilayer also helps maintain a specific chemical climate. Additionally, cholesterol is a lipid that alters the flexibility of the cell membrane. Hence, "All of these" would be the best option.
