Question

Quizplus · Accepted Answer

Receptor sites on the outer surface of the plasma membrane are made of proteins. These proteins act as gatekeepers, allowing specific molecules to enter or exit the cell, and triggering specific cellular responses. CAMs (cell adhesion molecules), carbohydrates, lipids, and keratin are also components of the plasma membrane, but do not specifically make up receptor sites.
