Active transport Passive transport Protein Pumping Simple Diffusion Exocytosis Osmosis Endocytosis Facilitated Diffusion Moving from LOW concentration to HIGH concentration Moving from HIGH concentration to LOW concentration Moving UP or AGAINST the concentration gradient Moving DOWN or with the concentration gradient ATP energy IS required ATP energy IS NOT required Moves cells away from equilibrium Moves cells closer towards equilibrium Cytoplasm membrane fluid extracellular Cytoplasm extracellular fluid Star Star ATP membrane Channel Pump Pump Pump PTl P ATP PTl P Protein Channel ATP P PT lP Cell transport over the plasma membrane that requires the CELL to do WORK! Cell transport over the plasma membrane that DOES NOT require the CELL to do WORK! Water moves out of the cell From hypertonic To hypotonic This is why desalination uses so much electricity to remove salt from sea water. From hypotonic towards hypertonic
