Question

Identify the main components which make up the lipid bilayer of the cell membrane, and contain hydrophobic and hydrophilic regions are

• A. Cholesterol molecules, which increase membrane fluidity
• B. Glycoproteins, which can serve as surface antigens
• C. Glycolipids, since the lipid portion of the molecule is hydrophobic
• D. Phospholipids, which contain hydrophobic fatty acid tails

Answer 1

Answer: (D)

Phospholipids, which contain hydrophobic fatty acid tails

Phospholipids which form the bilayer contains phosphate group which is hydrophilic and fatty acyl tails that are hydrophobic

So, the correct answer is'Phospholipids, which contain hydrophobic fatty acid tails'
