Which of the following substance is most favourable to form the structural components of biological membranes?
Correct answer: C. Both a and b
- A. Hydrophilic Carbohydrates
- B. Hydrophobic fats
- C. Both a and b
- D. None of these
Explanation
Option A : Carbohydrate groups are present only on the outer surface of the plasma membrane and are attached to proteins, forming glycoproteins, or lipids, forming glycolipids. Option: B Hydrophobic fats are the most favourable substance to form the structural components of biological membranes. All membrane lipids are amphipathic i.e. they contain both, a hydrophilic region as well as a hydrophobic region.
