773023671Hydrophilic ComponetPhosphate group
773023672Hydrophobic ComponetFatty Acid Tails
773023673Plasma Membrane FunctionsTransports Specific Solutes, Enzymatic Activity Signal Transduction Cell to cell recognition intercellular joining maintain cell shape
773023674Hypertonic solution AnimalCell shrinks
773023675Hypertonic solution plantWater exits cell can lead to plasmolysis
773023676Hypotonic solution animalcauses cell to swell
773023677Hypotonic solution plantcauses cell to swell until cell wall intervenes, cell is then turgid
773023678Isotonic solution animalNothing happens
773023679Isotonic solution plantNo movement of water in or out, cell becomes flaccid (limp) then wilts
773023680Plasmolysiscell membrane pulls apart from cell wall
773023681aquaporinchannel protein for h2o
773023682Amphipathicboth hydrophobic and hydrophillic
773023683glycoproteinCarb group attached to a peripheral protein
773023684Passive transportno energy required
773023685Active transportrequires energy
773023686OsmosisMovement of water across a selectively permeable membrane
773023687Osmotic pressureAbility of osmosis to generate enough pressure to lift a volume of water
773023688Diffusionmovement of particles from high to lower concentrations
773023689Concentration GradientDifferences in concentrations
773023690Facilitated Diffusionuses carrier molecules/proteins follows concentration gradient
773023691PhagocytosisFood, cells take in solids rather than liquids
773023692PinocytosisCells take in droplets of a liquid
773023693Receptor mediated endocytosisligands binds to receptor specificity
773023694Activation energyenergy required to start a reaction
773023695Enzymensend in -ase, is a catalytic protein, regulates metabolic pathways
773023696GlycolysisAnaerobic, occurs in cytoplasm, produces 4 ATP 2 CO2 Acetyl CoA 2 NADH
773023697Oxidation ReactionSubstrate loses electrons
773023698Reduction reactionSubstrate gains electrons
773023699Citric acid cycleOccurs in Matric, produces 6 NADH+H, 2 FADH2, 2 Co2, 1 ATP (This is per turn X2 per glucose)
773023700Electron Transport ChainOccurs in cristae, produces 32 ATP and H2O
773023701Substrate level PhosphorylationGlycolysis and Citric Acid Cycle
773023702Oxidative PhosphorylationETC
773023703ATP SynthaseEnzyme, turns ADP to ATP
