Biological Consequences of Membrane Fluidity and Fusion
In the previous chapter, we saw that the lipid constituents of membranes confer on these structures a fluid character. Membrane fluidity allows for a variety of biological functions. These include cell infection by envelope viruses; cell fusion, as it occurs in the biogenesis of a muscle fiber (a myotube); and the formation of junctions between cells, to allow intercellular communication. It is also clear that exoand endocytosis would be impossible in cells possessing rigid membranes.
