The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.
What the person said above me
A) the common cold is the most infectious disease.
Charles Darwin has the first or the origin of the bipedalism
hypothesis. Human beings are compared to
apes and he also suggested enormous brain and upright locomotion were link. He
also suggested human evolved into larger brains when still
ape-like-tree-dwellers. Humans are bipedal because they have free hands to
carry and manipulate tools and having tool-use, lost their project canning.
