5 Matching questions

  1. defensive
  2. glycerol
  3. saturated fat
  4. quaternary structure
  5. unsaturated fat
  1. a an alcohol with three carbons, each having a hydroxyl group
  2. b the 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. c the type of protein that protects against disease; example: antibodies combat bacteria and viruses
  4. d a fat made from unsaturated fatty acids; they are liquid at room temperature (oils) because kinks in -cis bonding prevent molecules from packing together to solidify
  5. e 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 Multiple choice questions

  1. protein molecules that assist in the proper folding of other proteins; they do not specify the final structure of a protein, instead they keep the new polypeptide separated from "bad influences" in the cytoplasmic environment while it folds
  2. links that form where two cysteine monomers are brought together by folding of protein; covalent bonds reinforce structure
  3. an inherited blood disorder that is caused by a substitution of one amino acid (valine) for the normal amino acid (glutamic acid) at a particular position in the primary structure of hemoglobin, the protein that carries oxygen in red blood cells
  4. the shape of proteins that are long and fiber-like
  5. the type of protein that selectively accelerates chemical reactions; example: digestive enzymes release polymers in food

5 True/False questions

  1. structuralan alcohol with three carbons, each having a hydroxyl group

          

  2. nucleotidethe 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

          

  3. cholesterola 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

          

  4. storagelipids characterized by a carbon skeleton consisting of four fused rings

          

  5. 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
