5 Multiple choice questions

  1. small nitrogen containing molecules, amino acids, are joined to form dipeptides which are joined to form polypeptides which may be joined to other polypeptides to from proteins. Proteins have unique 3 dimensional shapes or configurations that enable them to function as enzymes to catalyze reactions and function in other active ways.
  2. = glycerol + fatty acid.
    are another source of energy but some may contribute to heart disease. Most plant __ are unsaturated oils and most animal __ are saturated.
  3. molecules of carbon + hydrogen
  4. forms our genes,
  5. are parts of a molecule that participate in a chemical reaction

5 True/False questions

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


  2. Atomic Number=number of protons


  3. Atomic Mass=...=...number of protons


  4. Levels of Protein structurePrimary 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


  5. Common Features of lifeOrder, regulation, growth & development, energy processing, response to the environment, reproduction, evolutionary adaptation
