Membrane Revision
-
Osmosis
net movement of solvent molecules from high conc. to low conc. across a partially permeable membrane
-
-
-
-
-
-
-
Diffusion
Simple
small, non-polar molecules in high conc. on one side of membrane can easily pass through bilayer
Facilitated
-
protein channels, carrier proteins
-
