| 5957243212 | Selectively Permeable | a property of cell membranes that allows some substances to pass through, while others cannot | 0 | |
| 5957243213 | Phospholipid Bilayer | double layer of phospholipids that makes up plasma and organelle membranes | 1 | |
| 5957243214 | Integral Proteins | penetrate the hydrophobic core and often span the membrane | 2 | |
| 5957243215 | Peripheral Proteins | Bound to the inner or outer surfaces of the membrane and are easily separated from it. | 3 | |
| 5957243216 | Glycoproteins | proteins that have carbohydrates covalently bonded to them, often for self vs foreign recognition | 4 | |
| 5957243218 | Passive Transport | any transport that does not require the cell to expend energy (always from a high to low concentration) | 5 | |
| 5957243219 | Active Transport | energy-requiring process where a substance moves against the concentration gradient (low to high concentration) | 6 | |
| 5957243220 | Diffusion | net movement of a substance down a concentration gradient (high to low) | 7 | |
| 5957243221 | Facilitated Diffusion | diffusion of solutes across a membrane, with the help of transport proteins | 8 | |
| 5957243222 | Osmosis | diffusion of water across a selectively permeable membrane | 9 | |
| 5957243223 | Hypertonic | solute concentration is greater than inside the cell, cell loses water | 10 | |
| 5957243224 | Hypotonic | solute concentrations in less than inside the cell, cell gains water | 11 | |
| 5957243225 | Isotonic | solute concentrations are the same on both sides of the membrane, cell does not gain or lose water | 12 | |
| 5957243226 | Sodium-Potassium Pump | actively pumps Na+ ions out and K+ ions in, 3 Na leave for every 2 K that enter | 13 | |
| 5957243227 | Proton Pump | pumps (H+ ions) out of the cell, creating a proton gradient, protons then diffuse back into the cell, this is used to power the production of ATP | 14 | |
| 5957243228 | Contransport | process where single ATP-powered pump actively transports one solute out and indirectly drives the transport of other solutes in (against their concentration gradient) | 15 | |
| 5957243229 | Exocytosis | exporting materials by fusion of vesicles with the plasma membrane | 16 | |
| 5957243230 | Endocytosis | importing materials by forming vesicles derived from plasma membrane | 17 | |
| 5957243231 | Phagocytosis | part of the cell membrane engulfs LARGE particles or entire cells (cell eating) | 18 | |
| 5957243232 | Pinocytosis | part of the cell membrane engulfs SMALL dissolved substances or fluid droplets in vesicles (cell drinking) | 19 | |
| 5957243233 | Receptor-Mediated Endocytosis | importing of specific macromolecules by receptor proteins bind to a specific ligand which triggers the inward budding of vesicles formed from coated pits | 20 | |
| 5957243234 | Ligands | molecule that binds to the specific receptor site on another molecule | 21 | |
| 5957243236 | Fluid Mosaic Model | states that the membrane is a fluid structure with a mosaic of various proteins embedded in it | 22 | |
| 5957243237 | Cholesterol | found in the cell membrane and contributes fluidity, less fluid at warmer temperatures, more fluid at lower temperatures | 23 | |
| 5957243238 | Transport Proteins | allow passage of hydrophilic/polar substances across the membrane | 24 | |
| 5957243239 | Concentration Gradient | spectrum of ion concentration. Ions tend to move from high concentration to low concentration | 25 | |
| 5957243240 | Turgor Pressure | outward force exerted by the water-filled central vacuoule. The cell becomes firm | 26 | |
| 5957243241 | Gated Channels | protein channel in a cell membrane that opens or closes in response to a particular stimulus | 27 | |
| 5957243242 | Aquaporins | proteins that facilitate the passage of water into a cell | 28 | |
| 5957243244 | plasmolysis | As a plant cell loses water, it shrivels, and its plasma membrane pulls away from the cell wall | 29 | |
| 5957243245 | crenation | Condition wherein animal cells decrease in size, shrivel and wrinkle, and are no longer functional when in a hypertonic solution | 30 | |
| 5957243248 | water potential |  | 31 | |
| 5967297660 | alpha-helix protein | specific spiraled protein that spans the membrane and is involved in receptor function | 32 | |
| 5967320525 | plasmodesmata | cell to cell connection in plants that allows movement of water and other materials | 33 | |
| 5967350374 | unsaturated fatty acid tails | double carbon bond results in a "bent" structure that provides FLUIDITY to the cell membrane. | 34 |
