The factors affecting the rate of permeability in a cell membrane? The plasma membrane is a permeable membrane, and it controls exchanges between the cell inner and outer environment. The rate of membrane permeability is dependent on a many factors. These are: * Molecular size of the solute as the permeability mostly decreases with increasing size * Lipid solubility's permeability usually increases with increasing fat or oil solubility * The degree of ionization as permeability mostly decreases with increased ionization * The pH and temperature also have great effect on the permeability of the plasma membrane and in the experiment I will test how temperature has an effect on the rate of permeability. Roles of the components of cell membranes: My study has shown me that cell membranes contain many different types of molecules and they each have different parts to play in the overall structure and function of the membrane, these molecules are; Phospholipids - these forms...
