5 Matching Questions

  1. primary structure
  2. polysaccharides
  3. beta pleated sheet
  4. saturated fat
  5. contractile and motor
  1. a the type of protein that controls movement; example: actin and myosin are responsible for the contraction of muscles; other proteins are responsible for the undulations of cilia and flagella
  2. b macromolecules; polymers with a few hundred to a few thousand monosaccharides joined by glycosidic linkages; serve as storage material, hydrolyzed as needed to provide sugar for cells; building material for structures that protect a cell or an organism; architecture and function are determined by sugar monomers and by positions of glycosidic linkages
  3. c a secondary structure in which two or more regions of the polypeptide chain lying side by side are connected by hydrogen bonds between parts of two parallel polypeptide backbones; it makes up the core of globular proteins
  4. d a fat made from saturated fatty acid; animal fats are solid at room temperature because they lack double-bonds, thus flexibility enables molecules to pack together tightly
  5. e the unique structure of amino acids; example: a polypeptide composed of 127 amino acids has 20^127 different ways it can be organized

5 Multiple Choice Questions

  1. a long molecule consisting of many similar or identical building blocks linked by covalent bonds, much as a train consists of a train of cars; carbohydrates, nucleic acids, and proteins are examples of these
  2. the sugar connected to DNA; has one less oxygen atom than the other sugar associated with nucleic acids
  3. giant molecules formed by the joining of smaller molecules, usually by a condensation reaction; polysaccharides, proteins, and nucleic acids are considered these
  4. an alcohol with three carbons, each having a hydroxyl group
  5. chemical agents that selectively speed up chemical reactions without being consumed by the reaction; can be seen as workhorses that keep cells running by carrying out processes of life

5 True/False Questions

  1. defensivea discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses)

          

  2. quaternary structurethe overall protein structure that results from the gathering of polypeptide subunits; some proteins consist of 2 or more polypeptide chains combined into one macromolecule

          

  3. deoxyribonucleic acida 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

          

  4. dehydration reactionwhen two monomers connect to each other by a reaction in which two molecules are covalently bonded to each other through a loss of a molecule

          

  5. ribonucleic acida type of nucleic acid consisting of nucleotide monomers with a ribose sugar and nitrogenous bases adenine, cytosine, guanine, and uracil; usually single-stranded; functions in protein synthesis, gene regulation, and as the genome of some viruses
