WebTo perform these roles, the plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates (sugars and sugar chains), which decorate both the proteins and lipids and help cells recognize each other.

"Web(1) 3 Na+ ions are removed from the cell across the basolateral membrane in exchange for 2 K+ ions using the Na+-K+ ATPase. (2) The 3Na -2K+ exchange creates a gradient for Na+ movement out of the cell. (3) The Na+- K+- 2Cl- co-transport moves one Na+, one K+ and two Cl- ions into the cell across the basolateral membrane.
