Review CH: 5 Explain the types of passive transport. Diffusion: movement of molecules from an area of higher conc. to an area of lower concentration Example: Food coloring added to water (S.A) Osmosis: movement of water from an area of higher concentration to an area of lower concentration (S.A) Facilitated Diffusion: movement of molecules from an area of higher concentration to an area of lower concentration by using carrier proteins Ion Channels: movement of ions across the cell membrane through small passageways Explain the types of active transport. Sodium-Potassium pump: movement of ions from an area of lower concentration to an area of higher concentration by the use of energy ( 3 Na+ are pumped outside and 2 K+ are pumped inside) Endocytosis: process by which cells ingest large particles or other cells Examples: pinocytosis-drinking and phagocytosis-eating (S.A) Exocytosis: process by which particles are expelled or removed from the cell (S.A) Determine what type of solution a cell was placed in. Draw picture Isotonic: concentration of solutes is equal inside and outside of the cell water moves back and forward at the same rate cell does not change Hypotonic: concentration of solute outside the cell is lower concentration of water outside the cell is higher water moves into the cell cell swells Hypertonic: concentration of solute outside the cell is higher concentration of water outside the cell is lower water moves out of the cell cell shrinks Define Concentration gradient: difference in the concentration of molecules across a space Equilibrium: condition in which the concentration of molecules of a substance is the same throughout a space Contractile vacuole: collects excess water and pump it out Turgor pressure: pressure that water molecules exert against the cell wall Carrier protein: protein in cell membrane that moves molecules across the membrane Factors why a molecule may not pass through a cell membrane Size Soluble in the cell membrane Charged (ion-Na+, Cl -) Matching Equilibrium Contractile vacuole Concentration gradient Turgor pressure Carrier protein Hypertonic Hypotonic Isotonic
