-proetin alltic enzyme? -amino acid sequence primary sequence -hydrophobic bonds almost as strong as hydrogen bonds -chaperone? = made of many proteins -heteropolymer = α 2 β 2 -heme -when proteins bind together, they alter the structure of each other -lipids are soluble in hydrophobic solvent (organic solvents) -hydrophobic solvent = organic solvent -energy glycogen OR triglycerides adipocyte -fat (solid) vs. oil (liquid) -phosphotidic acid -phosphosidyl choline (PC) -amphipathic -hydrophobic bonds within micelle -plasmodesmata = allow fluid flow between plant cell walls -adding fatty acid unsaturated is more effective than cholesterol when cell moves to colder environment -carbohydrates on inside of cell -when solute dissolve in water, water will move down its concentration gradient -equilibrium = when rate of movement of water across membrane are the same -osmotic pressure -plant cell in hypotonic will gain turgor pressure, but be normal (turgid) -in isotonic, plant cell will be flaccid

Unformatted text preview: -in hypertonic solution, plant cell will be plasmolyzed-animal cell will be lysed in hypotonic, normal in isotonic, and shriveled in hypertonic-hydrophobic substances move thru membrane quickly-alcohols, methane are hydrophobic, thus move with ease-membrane has aqua porum , pores channels-proton pump xfer H + out of cell-sucrose-H +-cotransporter xfer into cell-symport vs. antiport depend simply on where site is and in which direction-Na + , K + active pump – pump out 3 Na + , pump in 2 K +-electrogenic pump accumulate charged ions inside/outside, outside is zero, inside is negative-receptor proteins-transduction = xfer of one energy form to another -spontaneity = tendency of change to proceed spontanesouly-free energy at equilibrium is 0-ATP is a catalytic molecule-conformers?-feedback inhibition to stabilize the system-cofactor-more reduced compounds have more energy-fluorescence = photon coming out from excited state-cholorophyll has Mg...
