What Factors Affect the Permeability of a Cell Membrane
Apr 03 2020 · The permeability of a cell membrane is affected by the polarity electric charge and molar mass of the molecules that diffuse through it. The phosolipid layers that make up the cell membrane also affect its permeability. A cell membrane consists of two phosolipid layers. Each layer has an electrically charged and hydrophilic head while the
