Document Summary
Plasma membrane: a phospholipid bilayer in which lipid and protein molecules are held together mainly by non- The internal face of the membrane is known as the cytosolic face (oriented toward the interior of the cell). The external face of the membrane is known as the exoplasmic face (oriented toward the environment). The hydrophobic core of the plasma membrane prevents the diffusion of hydrophilic molecules across the. Functions of the plasma membrane: define the boundaries of the cell and to serve as permeability barriers, the plasma membrane interior is a hydrophobic region that acts as an effective permeability. Barrier for hydrophilic molecules and ions: functions as a site for specific proteins and specific functions, the plasma membrane contains specific functions because the molecules and structures. Fluid mosaic model - s. jonathan singer & garth nicolson (1972) The fluid mosaic model envisions a membrane as a mosaic pattern of proteins embedded fully or partially within a.
