Question

Quizplus · Accepted Answer

CAMs (cell adhesion molecules) do not serve as binding sites for specific ions. They serve as binding sites for other cells or extracellular matrix molecules for cell-to-cell communication or adhesion. Channels and carriers are both types of membrane proteins that facilitate the transport of molecules across the membrane. Channels are water-filled pathways that allow specific ions or small molecules to pass through, while carriers are more selective and bind specific solutes to transport them across the membrane. Proteins and carbohydrates may work together as glycoproteins to facilitate cell recognition and communication.
