1. Cellular Transport How Your Cells Eat, Drink and be Merry!

2. Do Your Cells Eat and Drink? Cells must take in water and nutrients in order to function. Mmm…..

3. What part of the cell allows it to take in nutrients and water?

4. Of What is the Cell Membrane Made? Proteins and Lipids

5. What are the Proteins in the Cell Membrane? Receptor Channel Marker

6. SO….. How DO Your Cells Eat, Drink and be Merry?

7. Cells move substances through the cell membrane by a process called transport Two Types of Transport: –Passive Transport –Active Transport

8. What is Passive Transport? Requires no energy from cell. Molecules move from high concentration to low concentration. Molecules move with the concentration gradient.

9. What’s happening?

10. How would diffusion happen in a cell?

18. Osmosis is a type of diffusion Cell Membrane

35. Explain what is happening

43. How does Passive Transport affect my cells?

44. What would happen to the animal cells in each beaker? 100% Distilled Water 80% H 2 O 70% Water 30% Dissolved Substances 80% H 2 O 80% Water 20% Dissolved Substances 80% H 2 O

45. Which way did the water move? 100% Distilled Water 80% H 2 O Why did the cell get so big?

46. Which way did the water move? 80% Water 20% Dissolved Substances 80% H 2 O Why did the cell stay the same size?

47. Which way did the water move? 70% Water 30% Dissolved Substances 80% H 2 O Why did the cell get so small?

48. REVIEW 1.What part of the cell regulates what goes in and out? 2.What are the two components of the cell membrane? 3.What are the two types of transport? 4.What are the characteristics of passive transport?

49. MORE REVIEW 1.Explain diffusion. Why does it occur? 2.Explain osmosis. Why does it occur? 3.Explain facilitated diffusion. 4.What is the role of the channel protein in facilitated diffusion?

50. Even MORE Review! 1.What happens to an animal cell when there are more dissolved substances on the outside of the cell? 2.The inside? 3.When there are equal amounts?

51. How is Active Transport different? 1.Active transport requires energy. 2.Molecules move from low concentration to high concentration 3.Molecules move against concentration gradient.

52. What is this cell doing?

53. Endocytosis Cells bring large in particles using cell membrane –There are 2 types: Phagocytosis Pinocytosis Channel proteins are used to bring in large molecules. http://w3.uokhsc.edu/human_physiology/ATPase.htm

54. Phagocytosis Your white bloods cells also do this. This is the ingestion of large particles. Amoeba

55. Pinocytosis Tiny pockets form along cell membrane, and pinch off into vacuoles inside the cell. Sometimes called “Cell Drinking”

56. Exocytosis This is how the cell gets rid of waste.

57. REVIEW 1.How is Active transport different from passive? 2.What part of the cell is used to bring in particles? 3.How does a cell (including white blood cells) take in LARGE particles? 4.How does a cell take in small or liquid particles?
