BIOL 1107 Lecture Notes - Lecture 38: Amphiphile, Osmosis, Hydrophile
Document Summary
Plasma membranes are made up of a lipid bilayer of phospholipids: phospholipids don"t dissolve in water. Micelles: heads face the water and tails face each other (in a circular shape the heads on the outside and tails inside the circle) Term for having a hydrophobic and a hydrophilic region in. Plasma membranes are selectively permeable. amphipathic. o. Ions and molecules diffuse spontaneously: move from regions of higher concentrations to ones of lower concentrations, osmosis: movement of water across the plasma membrane.
