The plasma membrane around a eukaryotic cell is composed of:
A)hydrophilic fatty acyl side chains.
B)hydrophobic phospholipids.
C)a phospholipid bilayer.
D)none of the above

Question

Quizplus · Accepted Answer

The plasma membrane of a eukaryotic cell is made up of a phospholipid bilayer, which consists of hydrophobic tails facing each other and hydrophilic heads facing outward. Therefore, option C is the correct choice. Option A is incorrect because fatty acyl side chains are not hydrophilic. Option B is also incorrect because phospholipids are amphipathic, meaning they have both hydrophilic and hydrophobic properties, but the membrane is not composed solely of the hydrophobic portion of the phospholipids. Option D is incorrect because one of the options A, B, or C must be correct.
