Which of the following substance is most favorable to form structural component of biological membranes___________?
Correct answer: B. Hydrophobic fats.
- A. Hydrophilic Carbohydrates
- B. Hydrophobic fats.
- C. Both a and b
- D. None of these
Explanation
Membrane structure is based mainly on amphipathic lipids, whose hydrophobic portions form the interior barrier and whose hydrophilic portions face water. Hydrophilic carbohydrates alone cannot form the main membrane bilayer, so students may incorrectly choose both a and b.
