| Protein pore | Aquaporin |
| Proteins (most integral proteins) span the entire lipid bilayer | Transmembrane proteins |
| Proteins attach to the inner or outer surface but do not extend through the membrane | Peripheral proteins |
| Membrane proteins with a carbohydrate group attached that protrude into the extracellular fluid. | Glycoproteins |
| Functions of Membrane Proteins: Forms a pore through which a specific ion can flow to get across membrane. | Ion channel (integral) |
| Functions of Membrane Proteins: Transports a specific substance across membrane by undergoing a change in shape. | Carrier (integral) |
| Functions of Membrane Proteins: e.g. amino acids, needed to synthesize new proteins, enter body cells via carriers. | Carrier (integral) |
| Functions of Membrane Proteins: selectively moves a polar substance or ion from one side of the membrane to the other | Carrier (integral) |
| Functions of Membrane Proteins: known as transporters | Carrier (integral) |
| Functions of Membrane Proteins: Recognizes specific ligand and alters cell’s function in some way | Receptor (integral) |
| Functions of Membrane Proteins: for cellular recognition | Receptor (integral) |
| Functions of Membrane Proteins: Catalyzes chemical reactions | Enzyme (integral and peripheral) |
| Functions of Membrane Proteins: Anchors filaments inside and outside the plasma membrane, providing structural stability and shape for the cell. | Linker (integral and peripheral) |
| Functions of Membrane Proteins:May also participate in movement of the cell or link two cells together. | Linker (integral and peripheral) |
| Functions of Membrane Proteins: Distinguishes your cells from anyone else’s (unless you are an identical twin) | Cell identity marker (glycoprotein) |
| Serve as enzymes and linkers. | Peripheral proteins |
| Functions of Membrane Proteins: Major histocompatibility (MHC) proteins. | Cell identity marker (glycoprotein) |
| Transport processes: requires a specific channel or a carrier molecule, but no energy is used | Facilitated diffusion |
| Transport processes: involve the use of energy, primarily from the breakdown of ATP, to move a substance against its [gradient] | Active processes |
| Most common intracellular cation | Potassium |
| Vesicles fuse with the plasma membrane, releasing their contents into the extracellular fluid | Exocytosis |
| A combination of endocytosis and exocytosis | Transcytosis |
