Unformatted text preview: o Facilitated diffusion Diffusion: o Physical property of matter o Individual molecules move randomly, but the net effect in non-random o The force that moves them: G=H-TS (Free energy) o After breaking down: G=-S o Example: On which side do the molecules have greater free energy? The right side, less molecules, they will move towards the right What will happen if the molecules can move? Net movement? Energy change Osmosis: o The net movement of water across (through) a semi-permeable membrane Terminology of Solutions: o Hypertonic: more concentrated o Isotonic: equal concentration o Hypotonic: Less concentrated...
