DIFFUSION, OSMOSIS & ACTIVE X-PORT ACROSS CELL MEMBRANES by Professor Fink

Review of Transport Across Cell Membranes, including Diffusion, Osmosis, Carrier-Mediated Transport (Facilitated Diffusion and Active Transport), Endocytosis (Phagocytosis) and Exocytosis (Secretion). Included in the description of Diffusion are the factors that the Rate of Diffusion Across Cell Membrane, including temperature, concentration gradient, size (MW) of solute, lipid-solubility (water-solubility vs. lipid-solubility). Included in the description of Osmosis is a qualitative description of Isotonic Fluids, Hypotonic Fluids & Hypertonic Fluids. Included in the description of Carried-Mediated Transport is Active Transport Pumps, Symports and Antiports.
