5 Matching questions

  1. Supra Molecular Assemblies
  2. Lactose
  3. Conjugated Proteins
  4. Competitive Inhibition
  5. Polysaccharides (glycans)
  1. a amino acid with another component; glycoprotein; nucleoprotein; lipoprotein; phosphoprotein.
  2. b occupy the active site
  3. c glucose and galactose
  4. d 10s-100s of polysaccharides; storage molecules, i.e., cellulose, chitin, glycogen; linear or branched; made of similar or different subunits.
  5. e m. wt. = 10^6-10^9; ribosomes, enzyme complexes, contractile systems, microtubules.

5 Multiple choice questions

  1. N-acetyl muramic acid; important sugar acids in bacterial cell walls
  2. all hydrocarbons have CH2 units (bad for health); animals
  3. glucose and fructose; bad for teeth
  4. one or more double bonds (mostly between 9 and 10); Plant and animals in cold climates.
  5. DNA and RNA; Basic Unit- nucleotide; Building Blocks- a cyclic pentose sugar; phosphate; nitrogenous base. DNA lacks a hydroxyl group making it more flexible.

5 True/False questions

  1. Oligosaccharidesmost important are disaccharides; covalent linkages of two monosaccharides with the release of H2O (glycosidic bond). i.e. sucrose, lactose, maltose, etc.


  2. Maltoseglucose and galactose


  3. Organellesnucleus, mitochondria, golgi bodies, chloroplasts


  4. Tertiarythe actual sequence of the amino acids


  5. SecondaryThe overall 3D structure of the polypeptide chain. Held together by different bonds: peptide, ionic, hydrogen, covalent, sulfhydryl, etc. Prions are proteins that don't take their correct 3D shape and are harmful; mad cow disease.
