Intrinsic proteins include channel and carrier proteins for transport, and glycoproteins involved in cell adhesion and as receptors; glycolipids act as cell markers recognized by the immune system.

| Front | Examples of intrinsic proteins 2.1.5(b) |
|---|---|
| Back | - Channel proteins - hydrophilic channel for passive movement of polar molecules/ions across conc gradient - Carrier proteins - passive (across conc gradient) and active transport (against conc gradient) into cells, involves changing of protein shape - Glycoproteins - embedded in cell surface membrane with attached carb chains, role in cell adhesion and as receptors for chemical signals Glycolipids not example but relevant to glycoproteins - Glycolipids - similar to glycoproteins, they’re lipids with attached carb chains, called cell markers/antigens, recognized as self or non-self by immune system cells |
