3. Active Transport
Requires Energy (ATP) BECAUSE molecules are being FORCED from LOW concentration to HIGH concentration
3 Types:
Protein Pump
Exocytosis
Endocytosis

4. Protein Pump
Forces small molecules and ions against the concentration gradient
Low to High concentration
Requires Energy (ATP)
Different from Protein Channel & Facilitated Diffusion
Example = Sodium-Potassium Pump

6. Exocytosis Releasing Materials OUT of the Cell using vesicles
Example: Proteins packaged by the Golgi

7. Bringing Materials INTO the Cell 2 Types: Pinocytosis & Phagocytosis
Endocytosis
Bringing Materials INTO the Cell
2 Types: Pinocytosis & Phagocytosis

8. Bringing FLUID INTO the Cell using vesicles (mini-membranes)
Pinocytosis (Endo)
Bringing FLUID INTO the Cell using vesicles (mini-membranes)
“Cell Drinking”

9. Phagocytosis (Endo)
Bringing large SOLIDS (food, bacteria, etc.) INTO the Cell using vesicles (mini-membranes)
“Cell Eating”
