Fluid mosaic model of plasma membrane explain

WebThe fluid mosaic model describes the cell membrane as a tapestry of several types of molecules (phospholipids, cholesterols, and proteins) that are constantly moving. This movement helps the cell membrane maintain its role as a barrier between the inside and outside of the cell environments. Sort by: Top Voted Questions Tips & Thanks WebFluid 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 within the membrane is measured as its fluidity.
