WebMembrane fluidity, the mobility of lipid moieties in the lipid bilayer of the plasma membrane, plays an important role in cellular functions including carrier-mediated transport, ion exchange, energy transfer, and regulation of enzyme activity [88]. Wu and colleagues found that less membrane fluidity decreased cAMP content, and Na + -K ... WebAnswer (1 of 2): The fluid mosaic model stipulates that a cell membrane is made up of a phospholipids bilayer with various proteins associated with the membrane. A phospholipid bilayer consists of two monolayers of phospholipid molecules. The phosphate heads are hydrophillic so face towards the ...
