transport proteins are responsible for controlling passage across the
membrane
fluid mosaic model The membrane is a mosaic of protein molecules
bobbing in a fluid bilayer of phospholipids
fatty acid tails nonpolar, hydrophobic
fatty acid heads hydrophilic, polar
periphial proteins bound to the surface of the membrane
integral proteins penetrate the hydrophobic core (ones that span
the membrane are transmembrane protiens
How do cells recognize each other? by binding to molecules, often containing
carbohydrates, on the extracellular surface of the
plasma membrane

Glycolipids Membrane carbohydrates that are covalently
bonded to lipids.
Hypdrophobic molecules such as hydrocarbons that can dissolve
in the lipid bilayer and pass through the membrane
rapidly
Hydrophilic molecules that don't cross the membrane easily
(ions and polar molecules)
transport proteins allow passage of hydrophilic substances across the
membrane
carrier proteins bind to molecules and change shape to shuttle
them across the membrane
passive transport the diffusion of a substance across a membrane
with no energy investment
Diffusuion Spreading out of particles away from each other,
from an area of high concentration to an area of
low concentration. (move to where space is
available)
concentation gradient substances diffuse from high concentration---->
low concentration
Osmosis Diffusion of water through a selectively permeable
membrane
Isotonic when the concentration of two solutions is the
same (no net movement)
