Fluid-mosaic model of the plasma membrane
WebThe fluid mosaic model describes the plasma membrane as consisting of: a) a phospholipid bilayer with embedded carbohydrates. b) two layers of phospholipids with cholesterol sandwiched between them. c) carbohydrates and phospholipids that can drift in the membrane. d) diverse proteins embedded in a phospholipid bilayer. WebVerified by Toppr Fluid mosaic model was proposed by Singer and Nicolson in 1972. According to this model, the quasi-fluid nature of lipids enables lateral movement of proteins within the overall bilayer. This ability to move …
