Transport Notes
IMOW Osmosis:
Simple Diffusion
_____________ across the membrane from _____________ to _____________
concentrations
Facilitated Diffusion
Facilitate = help along. diffusion that needs a little help
Three ways with the cell membrane



Protein Carriers
_____________ that help move _____________ sized molecules from _____________
concentration to _____________ concentration across the cell membrane
Tunnels living in the membrane that help move things through
Endocytosis/Exocytosis
_____________ molecules (like sugars) ENTER/EXIT the cell by creating a little membrane
_____________ around the molecule and _____________ that pocket (vesicle)
The prefix “endo” means
The prefix “exo” means
Passive Transport
Movement across the membrane that is easily done _____________ _____________
OSMOSIS, SIMPLE AND FACILITATED DIFFUSION
_____________ = pass right on through
Active Transport
The ability of a cell to move particles from region of _____________ to _____________
This requires _____________ from the cell
This is called _____________ _____________ = movement across the membrane that is easily
done but with energy (ATP)
