3. Cellular
Transport

4. State Standard:
B-2.5 Explain how active, passive, and facilitated transport, serve to maintain the homeostasis of the cell.
SC State Standards

5. -The movement of solutes and solvents (water) into and out of cells is essential for the survival of the organism.

6. Homeostasis= necessity of all organisms to maintain constant or stable conditions
This depends on the amount of materials moving in and out of cell
Waste materials exiting from cellular processes
Oxygen and glucose needed for cellular respiration

7. Each cell exists in a fluid environment and the cytoplasm is also in a fluid state
This makes it possible for fluids to move in and out
Cell membrane is semipermeable (selectively permeable)
Some substances can pass through while others cannot
Substances pass through either by active or passive transport

Phosphate Heads
Hydrophilic-water loving
Hydrophobic-water hating
Fatty Acid Tails

10. Passive
Transport
Facilitated
Diffusion
Diffusion
Osmosis

11. Passive Transport The movement of molecules from to concentration.
No energy needed.

12. If cells are placed in a solution that is different in concentration from that of the cell, the cells may be damaged and even shrivel or burst!

14. Diffusion
The movement of solutes from to

15. The spreading out of molecules across a cell membrane until they are equally concentrated.

18. Osmosis
The movement of water molecules from to .

19. The movement of macromolecules through protein channels from to .
Facilitated Diffusion
The movement of macromolecules through protein channels from to .

20. Process by which some substances are not able to pass directly through a cell membrane but are able to enter the cell with the aid of transport proteins

22. Active Transport Air-lock Protein Endocytosis Exocytosis Pinocytosis
Phagocytosis
Pinocytosis

23. Active Transport
The movement of molecules from an area of concentration to an area of concentration.
Energy is required.

24. Airlock Proteins
When a carrier protein uses energy to move small molecules from to concentrations.

26. Endocystosis and Exocytosis occur when molecules are too large to pass through a cell membrane even with the aid of transport proteins

27. Exocytosis-
Substances leaving the cell without passing through the phospholipid bilayer.

28. Endocytosis
The movement of macromolecules into a cell without passing through the phospholipid bilayer.

30. Phagocytosis- solid macromolecules moving into a cell without passing through the phospholipid bilayer.

31. Pinocytosis- liquids with solutes moving into a cell without passing through the phospholipid bilayer.
