| Question | Answer |
| Active Transport | - Energy is needed ( O2 +Glucose - CO2 + H20) |
| Process from Active Transport | * Endocytosis ( particles enter): - Pinocytosis - Exocytosis * Exocytosis (particles exit) - The movement of particles through a cell membrane from a region of lower concentration to a region of higher concentration using the energy from the cell respiration |
| Process from Active Transport | * WHERE: Cell Mambrane |
| Independent, Controlled and Dependent Variables | |
| Passive Transport | - No energy needed * Diffusion: Movement of molecules from a region of higher concentration to lower concentration. * Simple: Through phospholipids * Facilitated: Through proteins |
| Simple Diffusion | |
| Facilitated Diffusion | |
| Rate of Diffusion | - Distance ( larger the slower the diffusion) - Charge - Steepness of concentration gradient - Diameter of molecules - Temperature |
| Osmosis | - The net movement of water molecules through a partially permeable membrane from a hypotonic solution. * PARTIALLY: Permable for water ONLY * PERMABLE: Can get in * Membrane |
| Hypotonic, Hypertonic and Isotonic Solution | Hypotonic: More water than molecules- Increases Hypertonic: Less water than molecules- Shrinks Isotonic: Concentrations of both solutions are equal- Stays the same |
