what is the fluid part of the fluid mosaic model?
plasma membrane
the fluid mosaic model explains various observations regarding the structure of functional cell membranes. according to this biological model, there is a lipid bilayer (two molecules thick layer) in which protein molecules are embedded. the lipid bilayer gives fluidity and elasticity to the membrane. small amounts of carbohydrates are also found in the cell membrane. the biological model, which was devised by sj singer and g. l. nicolson in 1972, describes the cell membrane as a two-dimensional liquid that restricts the lateral diffusion of membrane components. such domains are defined by the existence of regions within the membrane with special lipid and protein cocoon that promote the formation of lipid rafts or protein and glycoprotein complexes. another way to define membrane domains is the association of the lipid membrane with the cytoskeleton filaments and the extracellular matrix through membrane proteins. the current model describes important features relevant to many cellular processes, including: cell-cell signaling, apoptosis, cell division, membrane budding, and cell fusion. the fluid mosaic model is the most acceptable model of the plasma membrane. its main function is to give shape to the cell.
fluid mosaic model
the fluid mosaic model explains changes in structure and behavior of cell membranes under different temperatures, as well as the association of membrane proteins with the membranes. while singer and nicolson had substantial evidence drawn from multiple subfields to support their model, recent advances in fluorescence microscopy and structural biology have validated the fluid mosaic nature of cell membranes.
