converts it to water and oxygen tho so not harmful to cell
colligative properties
depend on number of solutes present in solvent
vapour pressure: pressure exerted by gas molecules that've evaporated from solvent
boiling point: point at which liquid becomes gas
freezing point: point where liquid becomes solid
solutes present in solvent disrupt the solvent structure because it binds to them so the packing is less orderly and thus changes would be observed to these properties
tight junctions
creates regions (apical, lateral) on cell
prevents passage of substances btwn 2 cells
tight seal
desmosome
holds cells tgth at certain points
gap junctions
connections btwn 2 cells that allow mixing of their cytoplasms
