Question

Quizplus · Accepted Answer

The plasma membrane consists mostly of lipids (phospholipids, cholesterol, and glycolipids) and proteins. The lipid component forms a bilayer that creates a selective barrier, while the proteins act as gatekeepers or transporters for molecules to enter or exit the cell. Carbohydrates are also present in the plasma membrane, mostly in the form of glycoproteins and glycolipids, and they play a crucial role in cell recognition and communication.
