Question

Membrane phospholipids
Options
A Have hydrophilic heads that face outward & are exposed to water
B Have hydrophobic tails that face inward & are shielded from water
C Both A & B are correct
Correct Answer
D None is correct
Correct Answer

Option C is the correct answer.

Detailed Explanation

In the phospholipid bilayer, the hydrophilic (water-loving) heads face outward, interacting with the aqueous environments inside and outside the cell. The hydrophobic (water-fearing) tails face inward, away from water, forming the interior of the membrane.

Hint

Do the heads love water and face out, and the tails fear water and face in?
