membrane proteins act as carriers or channels for the specific movement of various substances in to and out of the cells.

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.
Through proteins in the membrane.

The cell membrane is the special structure that allows materials to pass through, utilizing channels and transport proteins to facilitate the movement of water and sugars in and out of the cell. This selective permeability helps regulate the internal environment of the cell and maintain homeostasis.

These special structures are called protein gates or protein channels. Water is able to diffuse through the cell membrane since it is a small molecule. However, there are channels called aquaporins that allow water to enter the cell. A glucose molecule cannot just diffuse into a cell. There are glucose channels on the surface of the cell membrane that bind glucose molecules and allow them to enter the cell.
