Active Transport 7.4

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)

Graphic: Sodium-Potassium Pump

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

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
