The flashcards below were created by user Jacqui on FreezingBlue Flashcards. What would you like to do?


  1. Cellulose
    a plant structural polysaccharide
  2. Chitin
    an animal structural polysaccharide
  3. Diffusion
    How hydrophobic and very small uncharged polar molecules (ex oxygen and carbon dioxide) can cross through cellular membranes.
  4. Disaccharide
    A double sugar, consisting of two monosaccharides joined by dehydration synthesis.
  5. Exocytosis
    The cellular secretion of macromolecules by the fusion of vesicles with the plasma membrane.
  6. Endocytosis
    The cellular uptake of macromolecules and particulate substances by localized regions of the plasma membrane that surround the substance and pinch off to form an intracellular vesicle.
  7. Fat (triacylglycerol)
    A biological compound consisting of three fatty acids linked to one glycerol molecule.
  8. Fatty acid
    A long carbon chain carboxylic acid. Fatty acids vary in length and in the number and location of double bonds; three fatty acids linked to a glycerol molecule form fat.
  9. Fluid mosaic model
    The currently accepted model of cell membrane structure, which envisions the membrane as a mosaic of individually inserted protein molecules drifting laterally in a fluid bilayer of phospholipids.
  10. Glycogen
    Animal Storage Polysaccharide
  11. Glycolipid
    lipids with a carbohydrate attached. Their role is to provide energy and also serve as markers for cellular recognition
  12. Glycoprotein
    proteins which have carbohydrate groups attached to the polypeptide chain.
