Cell Transport
Active
Requires energy
Goes from low to high
Against the concentration gradient
Types
Sodium-potassium pump
Movement of sodium and potassium from low to high. Need a protein.
Endocytosis
The cell bringing in materials through the use of vesicles
Exocytosis
Cell releasing materials through eh use of vesicles
Phagocytosis
Cell "eating"
Pinocytosis
Cell "drinking"
Passive
Does not require energy
Goes from high to low
Goes with the concentration gradient
Types
Diffusion
Movement of molecules from high to low
Osmosis
Hypertonic
Moving water out the cell
Causes the cell to shrivel
Isotonic
equal on both sides
Hypotonic
Moving of water into the cell
Can cause the cell to "blow up" or undergo plasmolysis
movement of water from high to low
Facilitated diffusion
Movement of big molecules from high to low
Need the help of a protein
