plasm Membrane and Diffusion - Case Study ExampleDiffusion is a means of active beam which results from thermal, random movement of molecular particles from regions of high concentrations to regions of low concentrations(3). There are six factors which influence dispersions in nomadics, these includes Concentration gradient, size of the molecules involved, Distance travelled by the molecules, Temperature of the medium and the molecules, Solubility of the molecule and the surface heavens of the plasma membrane in which the molecule can carry out its activities, Hence the rate of diffusion is given by the ratio of the product of solubility, gradient, temperature, surface and the product of distance the molecules moves by the square cornerstone of the mass of the molecule. Diffusion can be classified into three categories or types, which include simple diffusion, leave diffusion and facilitated diffusion(3).Simple diffusion occurs when micro or small non-polar molecular particles go through a fluid (liquid or gases) mostly liquids through a lipid bilayer. This diffusion type is characterized by hydrophobic molecules sorrowful to hydrophobic regions without being rejected(3). Hydrophilic molecules do not participate in simple diffusion because they would be rejected when they move into the hydrophobic region of the membrane.Channel diffusion is a type of attainive transport which involves ancestry proteins in which the molecule moves through an open, aqueous pore and it can be regulated. Charged particles and ions can pass through the pore (1).
