1. Active Transport
7.4

2. Active Transport- pumps
Movement of molecules against the gradient
Uses carrier proteins
Move from lo hi
Moves ions like Na+, K+, and Ca++
Uses energy (ATP) to pump out molecules
ATP ADP + P (breaking a bond releases energy)

4. Active Transport-importing
Endocytosis: movement of large materials (polypeptides) into the cell by creating a vesicle from the cell membrane
Phagocytosis: “eating” or bringing in large solid particles ex: amoeba eating
Pinocytosis: “drinking” or bringing in fluid from outside the cell

6. Active Transport-exporting
Exocytosis: movement of materials out of the cell using a vesicle that fuses with the cell membrane and releases material outside
All is done through the golgi apparatus
