Biology ~ 1.4: Membrane Transport
  1. Fluid Mosaic Model
    1. Movement
      1. Simple Diffusion
        1. Passive
          1. High concentration to low
            1. Down concentration gradient
          2. Osmosis
            1. Down Ψ gradient
              1. Strong solution = lots of solute = low Ψ
              2. Across selectively permeable membrane
                1. WATER ONLY
                  1. Hypertonic
                    1. Lower concentration of water OUTSIDE cell
                      1. Water diffuses out of cell
                    2. Isotonic
                      1. Equilibrium
                      2. Hypotonic
                        1. Lower concentration of water INSIDE cell
                          1. Water diffuses into cell
                        2. Passive
                          1. Water displacement
                          2. Facilitated Diffusion
                            1. Passive
                              1. From high to low concentration
                                1. Help from carrier proteins
                                  1. ENERGY NOT REQUIRED
                                    1. Molecules too big to diffuse normally so they require help
                                      1. Eg: Glucose
                                    2. Active Transport
                                      1. Against concentration gradient
                                        1. Requires energy

                                            1. ADP
                                              1. Pi
                                        2. Rate of diffusion

                                              1. Increase
                                                1. Faster

                                                  1. Slower
                                                2. Membrane Proteins
                                                  1. Increase
                                                    1. Faster
