What function do cholesterol molecules serve within the cell membrane?

Question

Quizplus · Accepted Answer

Phospholipids are molecules composed of two parts: a hydrophilic (attracts water) phosphate head and a hydrophobic (repels water) lipid tail.
The cell membrane consists of a bilayer of phospholipids where the phospholipids line up tail-to-tail. This bilayer creates a hydrophobic region between two layers of lipids, making it selectively permeable.
Cholesterol molecules help stabilize the flexible phospholipid bilayer structure to prevent breakage.
Protein channels pass completely through the cell membrane. These proteins act as transport highways from molecular movement into and out of the cell.
