When tissues are injured or infected, chemical signals can be releases that affect the plasma membrane of cells that line the nearby blood vessels. These blood vessels cells (endothelial cells) respond to the chemical signals by displaying a type of glycoproteins on their surface.These proteins will attach to circulating white blood cells bringing them to the site of injury or infection. These glycoproteins would best be described as ________.

Question

Quizplus · Accepted Answer

The glycoproteins described in the scenario function as cell adhesion molecules (CAMs) which are involved in the process of leukocyte extravasation, or the movement of white blood cells from the blood vessels into the surrounding tissues. Transport proteins, G-proteins, and desmosomes are not directly involved in this process.
