Cellular Membranes: Fluid Mosaic of Lipids and Proteins

Selective Permeability: Allows some substances to cross it more easily than others. A phospholipid is an amphipathic molecule, meaning it has both a hydrophilic region and a hydrophobic region. Fluid Mosaic Model: The membrane is a fluid-structure with a “mosaic” of various proteins embedded in or attached to a double layer (bilayer) of phospholipids. The…
