Cell Transport Test Review Topics Passive Transport:
- Movement of molecules from [High] [Low]
- No energy needed
- Reaches equilibrium, then dynamic equilibrium
Diffusion – moves solute molecules
o Uses pores in cell membrane
o Be able to complete picture examples
Osmosis – moves water only
o Uses aquaporins – special membrane proteins that allow water through
o Be able to complete picture examples
. Hypertonic – more solute
. Hypotonic – less solute
. Isotonic – equal solute
Active Transport:
- Movement of molecules from [Low] [High]
- Energy (ATP) required
o ATP= adenosine triphosphate
o ATP energy held within bonds of phosphates
Cell Membrane Pumps
o Ex: Sodium-Potassium pump
Endocytosis – into cell
o Pinocytosis – small molecules and liquids
o Phagocytosis – large molecules and whole cells
Exocytosis – out of cell
