Unformatted text preview: is predicted by the model. Fluorescence recovery after photobleaching demonstrates the potential for membrane embedded proteins and lipids to move laterally at various rates, depending on inherent membrane fluidity/viscosity. Single particle tracking experiments show that individual molecules in the membrane may have a wide range of laterally mobility characteristics. Some do not move at all, others move freaquently, raidly and randomly. Freeze-fracture analyzed by SEM confirms the predicted presence of proteins embedded in a sea of lipids, and under certain circumstances, these proteins can move laterally within the bilayer. It is generally conceded that the fluid mosaic model accurately explains most , if not all, experimental observations on the behavior of biomembranes....
