  1. PreAP Bio Foldables

  2. Notes and Foldables • The first part of the power point should go in your notebook • Don’t forget CORNEL STYLE NOTES • The rest of the power point will go in there.

  3. Vocabulary (In notebook) • Hydrophobic – molecule that does NOT want to be around water ** NONPOLAR (ex: oil) • HATES WATER • Hydrophilic – molecule that wants to be around water -** POLAR (ex: sugar, salts, other waters) • LOVES WATER

  4. Phospholipids (In notebook) • Draw this diagram in your notes Phosphate Head HYDROPHILIC “Loves Water” HYDROPHOBIC “Hates Water” Lipid Tails

  5. Cell (or Plasma) Membrane(In notebook) Phospholipid Bilayers – lipid layers creates a water proof boundary for the cells (Purple Area)

  6. Cell (or Plasma) Membrane(In notebook) * Cell membranes control what enters or leaves the cells

  7. Vocabulary (In notebook) • Solute – a molecule that is being dissolved • Ex: salt or sugar will dissolve in water NOTICE: look how the water molecules orient themselves to the + or – solute ions Na+ (Sodium Ion) Cl- (Chlorine Ion)

  8. Vocabulary (In notebook) • Solvent – a molecule that can dissolve something • Ex: Water (the universal solvent)

  9. Vocabulary (In notebook) • Solution – made up of solvent and solutes Solute Solute Water Solute

  10. Vocabulary (In notebook) • Concentration Gradient – the difference between molecules (green hexagons) on opposite sides of the membrane

  11. Notice the difference between HIGH concentration and LOW concentration High Concentration Low Concentration

  12. IF they can, molecules will ALWAYStry to equal out on both sides

  13. Vocabulary (In notebook) • Equilibrium – when solute amounts are EQUAL everywhere (usually referring to both sides of a membrane)

  14. Vocabulary (In notebook) • Permeable– when molecules can cross a membrane

  15. Vocabulary (In notebook) • Selectively Permeable– when certain molecules are allowed to cross a membrane

  16. The rest of the slides go into your foldables…

  17. Cellular Transport Foldable

  18. Show Landscape vs Portrait orientation

  19. Cellular Transport Foldable While holding the paper in Landscape orientation, fold your sheet of paper along the long edge, but leave about 1cm (one finger width) at the bottom of the page

  20. Cellular Transport Foldable Cellular Transport Write “Cellular Transport” at the bottom of the page (the 1cm section)

  21. Cellular Transport Foldable Cellular Transport Open the page back up

  22. Cellular Transport Foldable Cellular Transport Fold the page along the short edge, BUT JUST crease the upper portion in half (crease down the blue dotted line)

  23. Cellular Transport Foldable Cellular Transport Fold each edge into the middle upper fold you just made and crease only in the upper section again.

  24. Cellular Transport Foldable Cellular Transport Cut along the dotted lines that are colored blue in this picture

  25. Cellular Transport Foldable SimpleDiffusion Facilitated Diffusion Active Transport Osmosis Cellular Transport Label the outside flaps with “Simple Diffusion”, “Osmosis”, “Facilitated Diffusion”, and “Active Transport”

  26. Cellular Transport Foldable Upper inside flap Picture of Simple Diffusion Upper inside flap Picture of Facilitated Diffusion Upper inside flap Picture of Osmosis Upper inside flap 2 Pictures for Active Transport Lower inside flap Describe Facilitated Diffusion Lower inside flap Describe Osmosis Lower inside flap Describe Active Transport Lower inside flap Describe Simple Diffusion Cellular Transport Draw the pictures and describe the transport from the following slides…

  27. Picture for SimpleDiffusionInside Upper Flap HIGH Concentration LOW Concentration

  28. Simple Diffusion (Inside lower flap) • (Vocabulary) Diffusion - ALWAYS moves solutes from High Concentration  Low Concentration(Down the concentration gradient) • Simple diffusion allows molecules to move through the phospholipidbilayer without needing help. • Diffusion NEVER needs energy (ATP)

  29. Simple Diffusion (Inside lower flap) • Examples: • 1) perfume/cologne will diffuse through the entire room when someone sprays it. • 2) if the room catches on fire, the students will diffuse from inside (High concentration) to outside (Low concentration) of students • 3) a child going down a slide is like moving down the concentration gradient.

  30. Picture for Facilitated DiffusionInside Upper Flap HIGH Concentration LOW Concentration

  31. Facilitated Diffusion (Inside lower flap) • Facilitated Diffusion ALWAYS moves from High Concentration  Low Concentration(Down the concentration gradient) • (Vocabulary) Facilitated diffusion - REQUIRES a helper transport protein to get solute molecules across the phospholipidbilayer. • Facilitated Diffusion NEVER needs energy (ATP)

  32. Facilitated Diffusion (Inside lower flap) • The solute molecules are either Too BIG or Too HYDROPHILIC to cross the lipid area of the phospholipid bilayer • Transport proteins act as a tunnel that solutes travel through.

  33. Picture for OsmosisInside Upper Flap HIGH Concentration LOW Concentration

  34. Osmosis (Inside lower flap) • Osmosis ALWAYS moves from High Concentration  Low Concentration(Down the concentration gradient) • Osmosis REQUIRES a helper transport protein to get WATER molecules ( ) across the phospholipidbilayer. • Osmosis NEVER needs energy (ATP)

  35. Osmosis (Inside lower flap) • (Vocabulary) Osmosis – Movement of water across a membrane • Water molecules will never be able to easily cross the lipid area of the phospholipidbilayer, but ALL CELLS NEED WATER • Aquaporin is the transport protein that acts as a tunnel that solutes travel through.

  36. 2 Pictures for Active TransportInside Upper Flap • NOTICE: There are two pictures for Active Transport. Put one picture above the other on the inside upper flap… Picture 1 Picture 2

  37. Picture 1 for Active TransportInside upper flap HIGH Concentration ATP LOW Concentration

  38. Picture 2 for Active TransportInside upper flap HIGH Concentration LOW Concentration

  39. Active Transport (Inside lower flap) • Active Transport ALWAYS moves from LOW Concentration  HIGH Concentration(AGAINST the concentration gradient) • (Vocabulary) Active Transport- ALWAYS REQUIRES ENERGY (ATP) and a helper transport protein to get solute molecules across the phospholipidbilayerAGAINST the concentration gradient • Active Transport ALWAYS needs energy (ATP)

  40. Active Transport (Inside lower flap) • Ex: Think of a bouncer at a popular club. When the cell (club) is full, and a solute (person) wants to try and get in, they have to PAY the bouncer to let them “sneak” by. Money would be like the cell paying ATP energy to make the protein channel (bouncer) let the solute (person) in.

  41. Active Transport (Inside lower flap) • Active Transport is the only kind of cell movement that REQUIRES energy to work.

  42. Tonic Solution Concentration Foldable (Use your other sheet of clean paper)

  43. Tonic Solution Concentration Foldable In landscape orientation again, fold your sheet of paper along the long edge leaving about 1cm (one finger width) at the bottom of the page

  44. Tonic Solution Concentration Foldable Tonic Solution Concentration Write “Tonic Solution Concentration” at the bottom of the page (the 1cm section)

  45. Tonic Solution Concentration Foldable Tonic Solution Concentration Open the page back up

  46. Tonic Solution Concentration Foldable Tonic Solution Concentration Fold over 1/3 of the page ( the folded section is about equal length to the non-folded section) and crease the top section to the middle line

  47. Tonic Solution Concentration Foldable Tonic Solution Concentration Repeat on the other side, folding the edge to the first crease to make the 2nd crease

  48. Tonic Solution Concentration Foldable Tonic Solution Concentration Cut along the blue dotted lines

  49. Tonic Solution Concentration Foldable Hypertonic Isotonic Hypotonic Tonic Solution Concentration Label the outside flaps with “Hypertonic”, “Isotonic”, and “Hypotonic”
