5 Matching questions

  1. Conjugated Proteins
  2. Secondary
  3. Enzymes
  4. Uncompetitive Inhibition
  5. Saturated
  1. a amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
  2. b The inhibitor binds to ES complex so that further reaction does not take place - either forward or backward.
  3. c Biological catalysts- specific for a chemical reaction; not used up in that reaction; Apoenzyme: protein.
    Co-factor: non-protein component; Coenzyme- organic cofactor (NAD, FAD); Holoenzyme-Apoenzyme + cofactor.
  4. d The localized twisting and folding of the polypeptide chain. A specific orientation in space. Two main types: the alpha helix and the beta sheet. Helix- parallel some of the strongest; alpha keratin-nails; spiderwebs. Pleated sheet- anti-parallel; Beta keratin- silk. 18% of all proteins are one of these two shapes; others are random coiling
  5. e all hydrocarbons have CH2 units (bad for health); animals

5 Multiple choice questions

  1. DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.
  2. m. wt. 10^3- 10^9; nucleic acids, proteins, lipids, polysaccharides. 4 most important to study.
  3. Needed to disrupt electronic configurations; physiological temperature and pressure too low for most chemical reactions to take place. Enzymes serve to speed up reactions by lowering activation energy.
  4. proteins and RNA
  5. the actual sequence of the amino acids

5 True/False questions

  1. Polysaccharides (glycans)10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.


  2. Tertiarythe actual sequence of the amino acids


  3. precursors from the environmentamino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.


  4. Hybridizationdiagnostic technique; denature and add a known fluoresced DNA. Don't have to know base structure.


  5. Carbohydratesgeneral formula (CH2O)n; subunits linked by glycosidic bonds; poly hydroxy aldehydes or ketones and their derivatives; functions- structural support, nutrient and energy.
