The Cell tissue layer AP Biology Phospho lipoides ? Phosphate head ? Phosphate attracted to water system deliquescent aquaphobic Fatty blistering repelled by water ? Fatty acid tails ? ? Arranged as a bilayer Aaaah, one of those structure mesh examples AP Biology Arranged as a Phospholipid bilayer ? Serves as a cellular barrier / b ready sugar diametric deliquescent heads H 2O salt non icy hydrophobic tails impermeable to charged molecules polar hydrophilic heads waste AP Biology lipids Cell tissue layer defines cell ? Cell tissue layer separates living cell from aqueous environment ? thin barrier = 8nm fatness accommodates some substances to cross more(prenominal) easily than others ? hydrophobic (nonpolar) vs. hydrophilic (polar) ? Controls traffic in & forth of the cell ? AP Biology Permeability to polar molecules?

? tissue layer becomes semi-permeable via protein channels ? specific channels allow specific material across cell membrane H 2O inside cell aa sugar NH3 AP Biology salt outside cell Cell membrane is more than lipids ? Transmembrane proteins embedded in phospholipid bilayer ? get to semi-permeabe channels protein channels in lipid bilyer membrane lipid bilayer membrane AP Biology Why be proteins the perfect molecule to conformation structures in the cell membrane? AP Biology 2007-2008 Classes of amino group acids What do these amino acids have in park? nonpolar & hydrophobic AP Biology Classes of amino acids What do these amino acids have in common? I translatable the polar ones the best! AP Biology polar & hydrophilic Proteins domains anchor molecule ? Within membrane ? gumshoe areas of protein nonpolar amino acids ? hydrophobic ? anchors protein into membrane ? On outer surfaces of membrane in fluid ? polar amino acids ? hydrophilic ? extend into AP Biology extracellular fluid & into cytosol Nonpolar areas of protein H+ H+ Examples...If you want to stuff a full essay, order it on our website: Ordercustompaper.com
