5 Matching questions

  1. fibrous
  2. dehydration reaction
  3. purines
  4. proteins
  5. disaccharide
  1. a molecule that consists of two monosaccharides joined by a glycosidic linkage
  2. b the family of larger nitrogenous bases in which its members have a six-membered ring fused to a five-membered ring; members are adenine (A) and guanine (G)
  3. c macromolecules that are constructed from one or more polypeptides, each folded and coiled into a specific three-dimensional structure; all made from same 20 amino acids; most structurally sophisticated molecule known
  4. d when two monomers connect to each other by a reaction in which a hydroxyl group covalently bonds to a hydrogen atom, which causes the loss of a water molecule in the process
  5. e the shape of proteins that are long and fiber-like

5 Multiple choice questions

  1. the family of smaller nitrogenous bases in which its members have six-membered rings of carbon and nitrogen atoms; members include cytosine (C), thymine (T), and uracil (U)
  2. a double-stranded, helical nucleic acid molecule consisting of nucleotide monomers with a deoxyribose sugar and the nitrogenous bases adenine, guanine, cytosine, and thymine; it is capable of replicating and determining the inherited structure of a cell's proteins
  3. the unique structure of amino acids; example: a polypeptide composed of 127 amino acids has 20^127 different ways it can be organized
  4. the monomer of nucleic acids that has three parts: 1) a nitrogenous base (A, C, G, T, U); 2) a give-carbon sugar (a pentose); 3) a phosphate group
  5. the collection of coils and folds that result from hydrogen bonds between repeating constituents of the polypeptide backbone (not the amino acid sides)

5 True/False questions

  1. condensation reactionwhen two monomers connect to each other by a reaction in which a hydroxyl group covalently bonds to a hydrogen atom, which causes the loss of a water molecule in the process

          

  2. triacylglycerolan alcohol with three carbons, each having a hydroxyl group

          

  3. glycerolan alcohol with three carbons, each having a hydroxyl group

          

  4. catalystsa process that occurs when the bonds between two monomers are broken by the addition of water molecules, with a hydrogen from the water attaching to one monomer and a hydroxyl group attaching to the adjacent monomer

          

  5. macromoleculesrepeating units that serve as building blocks of a polymer; smaller molecules; some also have functions on their own
