Hydrophilic tails face inward, away from water
B
Hydrophobic heads face outward, towards water
C
Hydrophobic tails face inward, away from water
D

검증된 단계별 안내1
Understand the structure of a phospholipid: A phospholipid molecule consists of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.
Recognize the environment of the cell membrane: The cell membrane is surrounded by water both inside and outside the cell, creating an aqueous environment.
Determine the orientation of phospholipids in the bilayer: In an aqueous environment, hydrophilic heads face outward towards the water, while hydrophobic tails face inward, away from the water.
Visualize the bilayer formation: The phospholipid bilayer is formed with hydrophilic heads on the exterior surfaces and hydrophobic tails sandwiched in the interior, creating a barrier that separates the cell's internal environment from the external environment.
Apply this understanding to the options given: The correct description of the phospholipid bilayer formation is that hydrophobic tails face inward, away from water, and hydrophilic heads face outward, towards water.
