  5. e hydrolytic enzymes are manufactured by the ER sent to the Golgi for finishing and repackaging in sacs called _________, ___________ merge with food vacuoles to digest food or destroy invading organisms -Abnormal __________ can cause diseases include Tay-Sachs - inability to break down lipids resulting in damage to nerves and brain

5 Multiple choice questions

  1. larger vesicles, membranous sacs that help in digestion, storage, or water removal
  2. Primary structure = sequence of amino acids
    Secondary structure = coiling to form an alpha helix or folding to form a pleated sheet - hydrogen bonding may be involved
    Tertiary structure - Overall, 3 - D shape, usually described as fibrous or globular
    Quaternary structure - many proteins have multiple peptide chains or subunits - how these fit together is called quaternary structure
  3. ibers that run through the cell providing support, movement, anchorage and movement of organelles, 3 types - microfilaments, intermediate filaments, microtubules - the microtubule organizing center is called the centriole
  4. lack a membrane enclosed nucleus
    Nucleoid region, Ribosomes, Plasma membrane, Cell wall, Capsule, Pili, Flagella
  5. molecules of carbon + hydrogen

5 True/False questions

  1. Lipidsthese are non-polar, hydrocarbons, which are composed of fat molecules. Fat = glycerol + fatty acid. _______ are 1) important components of cell membranes (phospho_______), 2) molecules (steroids) that regulate cell function, and 3) molecules (waxes) that protect other cells

          

  2. Covalent bondsstrong bonds where atoms share electrons - two or more atoms held together by a covalent bond are called a molecule

          

  3. Carbon skeletonchain of carbon atoms in an organic molecule

          

  4. Golgi Apparatus (Eukaryotic cells)houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope
