1 ACTIVE TRANSPORT Chapter 5 pg. 103-106

2 Active Transport Requires energy! Molecules move from an area of low concentration to an area of high concentration Move against the concentration gradient

3 1. Membrane pumps

4 Pumps – Transport proteins that use energy – (low  high) Protein transfers the molecule to the other side. Sodium-Potassium Pump: transports Na+ and K+ against (not down) gradient

5 2. Endocytosis Bring large molecules into cell 1.Material is engulfed by cell membrane. 2.Membrane makes a pouch. 3.Pouch then pinches off and makes a vesicle. 4.Vesicle binds with lysosome.

6 2. Endocytosis Phagocytosis: A form of endocytosis in which immune cells attack and kill bacteria

7

8 3. Exocytosis Moving large particles out of the cell (the reverse of endocytosis) Draw This

9 1.Finish Grape Lab 2.Finish “Transport Review” DUE MONDAY Grape Lab Transport Review Cell Chosen Chart (on model directions)
