Questions about your lab??
I’m stamping it today. Late stamps will reflect in your Work Habits section of gradebook.
I’ll be grading it on Mon/Tuesday during your Unit Assessment

We have a SEMI-PERMEABLE membrane…

There are three types of movement across the cell membrane:
1) Passive Transport2) Active Transport3) “Active” Transport
![Page 7: LEVEL ZERO VOICE CATALYST (10 minutes, individual work): 1 ... · 8/10/2015 · Assignment #9 Transport: The Complete Picture LO: To explain all methods of transport across a cell](https://reader035.vdocuments.site/reader035/viewer/2022071218/6051cde314a6fa4ded16dd28/html5/thumbnails/7.jpg)
There are three types of movement across the cell membrane:
1. Passive Transport – movement of particles from high concentration to low concentration
• examples: diffusion (gas), osmosis (water)
![Page 8: LEVEL ZERO VOICE CATALYST (10 minutes, individual work): 1 ... · 8/10/2015 · Assignment #9 Transport: The Complete Picture LO: To explain all methods of transport across a cell](https://reader035.vdocuments.site/reader035/viewer/2022071218/6051cde314a6fa4ded16dd28/html5/thumbnails/8.jpg)
2. Active Transport: Movement of particle from less concentrated to more concentrated
• Requires energy, ATP
![Page 9: LEVEL ZERO VOICE CATALYST (10 minutes, individual work): 1 ... · 8/10/2015 · Assignment #9 Transport: The Complete Picture LO: To explain all methods of transport across a cell](https://reader035.vdocuments.site/reader035/viewer/2022071218/6051cde314a6fa4ded16dd28/html5/thumbnails/9.jpg)
2. Active Transport: Movement of particle from less concentrated to more concentrated
• Requires energy, ATPSodium Potassium Pump: pumps Na (sodium) and K (potassium) against their concentration gradients using ATP
• Against concentration gradient: low concentration moving to high concentration

3. “Active” TransportEndocytosis: taking material into the cell by engulfing (surrounding) them in membrane
![Page 12: LEVEL ZERO VOICE CATALYST (10 minutes, individual work): 1 ... · 8/10/2015 · Assignment #9 Transport: The Complete Picture LO: To explain all methods of transport across a cell](https://reader035.vdocuments.site/reader035/viewer/2022071218/6051cde314a6fa4ded16dd28/html5/thumbnails/12.jpg)
Endocytosis: taking material into the cell by engulfing (surrounding) them in membrane
Phagocytosis (cell eating): large solid particles are engulfed
![Page 13: LEVEL ZERO VOICE CATALYST (10 minutes, individual work): 1 ... · 8/10/2015 · Assignment #9 Transport: The Complete Picture LO: To explain all methods of transport across a cell](https://reader035.vdocuments.site/reader035/viewer/2022071218/6051cde314a6fa4ded16dd28/html5/thumbnails/13.jpg)

Phagocytosis because…1. How amoebas capture
food particles2. Phagocytes are special
cells that defend against invading pathogens
