Cell Membrane Transport
  1. Passive Transport
    1. Do not use energy
      1. Molecules move with concentration gradient.
        1. High to low.
          1. Diffusion
            1. Is the movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
            2. Osmosis
              1. Move across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.
              2. Facilitated Diffusion
                1. Is the diffusion of molecules across a membrane through transport proteins.
              3. A concentration gradient is the difference in the concentration of a substance from one location to another.
          2. Active Transport
            1. Use energy
              1. Molecules move against concentration gradient.
                1. Active Transport
                  1. Drives molecules across a membrane from a region of lower concentration to a region of higher concentration.
                  2. Exocytosis
                    1. The opposite of endocytosis, is the release of substances out of a cell by the fusion of a vesicle with the membrane
                    2. Endocytosis
                      1. Phagocytosis
                        1. Is a type of endocytosis in which the cell membrane engulfs large particles.Liquid Particles
                        2. Pinocytosis
                          1. Particles solid
                          2. Is the process of taking liquids or fairly large molecules into a cell by engulfing them in a membrane.
