Abstract the mechanism of the stimulatory action of insulin on the transport of sugar across the plasma membrane of skeletal muscle cells was studied by. Permeability of molecules introduction: in the late 1800's, e overton discovered that substances that dissolve in lipids pass more easily into the cell.

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment (the extracellular. the correlation between gpat2 expression and cell surface topography, roughness and membrane permeability in mda-mb-231 cells. Thus, for example, to determine the effect of lipoid materials upon the permeability of the membrane, its permeability in the normal condition was first measured.
