What type of membrane proteins form a passageway through the plasma membrane?

Question

Quizplus · Accepted Answer

Channel proteins form a passageway or channel through the plasma membrane for the movement of molecules or ions. Carrier proteins also facilitate the transport of molecules, but they do not form a continuous passageway. Receptor proteins bind to specific molecules or ligands, while enzymes catalyze chemical reactions. Marker molecules are involved in cell recognition. Therefore, channel proteins are the best choice for this question.
