  1. A solution is composed of...: a solute and a solvent.
  2. Active Transport: Cells that must move materials up thier concentration gradient from an area of low concentration to high concentration.
  3. Active Transport is...: Against concentration gradient from low to high concentration.
  4. An example of Active Transport: Sodium Potassium Pump
  5. An example of facilitated diffusion: Glucose
  6. Carrier Protiens: Specific protiens in the membrane that are used for active transport.
  7. Concentration Gradient: The difference in the concentration of molecules across a space.
  8. Contractile Vacuoles: Organelles that remove water.
  9. Cytolysis: The bursting of cells
  10. Diffusion: The movement of molecules from an area of higher concentration to an area of lower concentration.
  11. Each carrier protein transports...: A specific molecule.
  12. Endo and exocytosis are used to transport what: Large quantities of small molecules into or out of cells at a single time.
  13. Endocytosis: The process by which cells engulf external fluids or macromolecules and bring them into the cell in a vesicle.
  14. Equilibrium: The concentration of molecules are the same throughout the space they occupy.
  15. Facilitated Diffusion: Uses carrier proteins to move molecules that cannot fit through the lipid bilaryer into/out of the cell.
  16. Facilitated Diffusion works in what directions: Both directions
  17. First step of Fac. Diffusion: 1. Carrier protiens bond to the molecule.
  18. Gated Protiens are gated because of: Electrical Signs, Stretching of the Membrane, or Enviormental Factors.
  19. Hypertonic: Solution outside of the cell has more solute than the solution inside
  20. Hypotonic: Solution outside the cell has less solute than the solution inside of the cell
  21. In active transport...: Energy is need
  22. In the absence of other influences diffusion will eventually cause...: the concentration of molecules to be the same throughout the space they occupy.
  23. Ion Channel: Protiens in which ions diffuse
  24. Ion Channels can either be...: Open or Gated
  25. Isotonic: Concentration of the solution is equal inside and outside the cell
  26. No energy is need in...: Facilitated Diffusion.
  27. Osmosis: The process in which water molecules move through an area of higher concentration to lower concentration.
  28. Osmosis does not require: Cells to expend energy.
  29. Passive Transport: The movement of substances across the cell membrane.
  30. Phagocytes: Cells that allow the lyosomes to fuse with the vesicles that contain the ingested bacteria and viruses.
  31. Phagocytosis includes...: solids
  32. Pinocytosis includes ...: fluids and solutes
  33. Plasmolysis: When cells shrink a way from the cell wall and turgor pressure is lost
  34. Second step of Fac. Diffusion: 2. Carrier protein changes shape.
  35. Sodium Potassium Pump moves...: three Na+ out of the cell and moves two K+ into the cell.
  36. The ability to diffuse across a membrane...: Depends on the size/type of the molecule and of the chemical nature of the membrane.
  37. The net direction of osmosis depends on...: The relative concentration of solutes on two sides of the membrane.
  38. The net movement of water into the cell: Hypotonic
  39. Third step of Fac. Diffusion: 3. Molecule is moved across the membrane.
  40. Three types of Passive Transport: Diffusion, Osmosis, and Facilitated Diffusion
  41. Turger Pressure: The pressure water molecules exert against the cell wall.
  42. Two types of Endocytosis: Pinocytosis and Phagoctosis
  43. Water moves...: Down its concentration gradient.
  44. What is a vesicle: A pounch that pinches off the cell membrane and becomes a membrane bound organelle.
  45. What is diffusion driven by: Kinetic Energy and the Molecules Posses
  46. Which organish has a contractile vacuole: The paramecia
