AB High-Yield  TermsLipid  bilayer:  a  thin  polar  membrane  made  of  2  layers  of  lipid  moleculesIntegral  membrane  protein:  a  protein  molecule  that  is  permanently  attached  to  the  biological  membranePeripheral  membrane  protein:  a  protein  that  adheres  only  temporarily  to  the  biological  membrane  with  which  it  is  associatedEndoplasmic  reticulum  (ER):  the  ER  functions  as  a  packaging  system  working  in  concert  with  the  Golgi  apparatus,  to  create  a  network  of  membranes  found  throughout  the  whole  cellGolgi  apparatus:  the  Golgi  apparatus  packages  proteins  inside  the  cell  before  they  are  sent  to  their  destination;  it  is  particularly  important  in  the  processing  of  proteins  for  secretionApical  membrane:  the  layer  of  plasma  membrane  on  the  side  toward  the  lumen  of  the  epithelial  cellsBasolateral  membrane:  the  fraction  of  the  plasma  membrane  at  the  basolateral  side  of  the  cell  which  faces  adjacent  cells  and  the  underlying  connective  tissueGap  junctions:  intercellular  channels  designed  for  intercellular  communicationTight  junctions:  barriers  that  regulate  the  movement  of  solutes  and  water  between  various  epithelial  layersAntiporter:  protein  or  complex  that  couples  the  transport  of  2  compounds  across  a  membrane  in  opposite  directionsUniporter:  protein  or  complex  that  transports  1  molecule  of  solute  at  a  time  down  the  solute  gradientSymporter:  protein  or  complex  that  couples  the  transport  of  2  compounds  across  a  membrane  in  the  same  directionAquaporins:  membrane  water  channels  that  facilitate  rapid,  highly  selective  water  transportNa+/K+-ATPases:  membrane  transporters  that  utilize  the  energy  of  ATP  hydrolysis  to  transport  sodium  into  and  potassium  out  of  a  cellCardiotonic  steroids:  endogenous  digitalis-like  factors  that  inhibit  the  Na+/K+-ATPasesABC  family  transporters:  ATP-binding  cassette  transporters  that  couple  the  energy  of  ATP  binding  and  hydrolysis  to  substrate  transportSLC  family  transporters:  solute  carrier  transporters  that  include  transporters  that  function  by  secondary  active  transport  and  facilitative  diffusion
