membrane proteins act as carriers or channels for the specific movement of various substances in to and out of the cells.
The structures that allow certain materials to pass through the cell membrane are Proteins. Some such Proteins are known as Channel Proteins, Carrier Proteins, Sodium-Potassium pumps, and Proton pumps just to name a few.

What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
