Document Summary
Everything we have talked about since the last exam through friday"s lecture. Determines the rate of movement of a molecule across the membrane (what unit 7 is mostly about) The movement of proteins, lipids, etc. in the lateral plane of the membrane. Diagram that distinguishes them can be found on an overhead! Temperature where the membrane goes from a crystalline gel state to a liquid crystalline state. The temperature for a given membrane where the membrane switches (in one step) from a gel state to a liquid gel state where the membrane is moveable, fluid, and more disordered. Behavior of phospholipids at a given temperature. Increases the density of the hydrophobic phase of the membrane (the part that"s inside with the hydrophobic tails) Makes the membrane less permeable at all temperatures. Video demonstrating membrane fluidity things moving in the membrane. Yellow fatty acid head groups (polar/charged) The yellow layer is the hydrophilic heads which are polar and charged.
