  4. allelomones
  5. discovery of hormones
  1. a a method to inactivate specific mRNAs
  2. b chinese discovered goiters due to enlarged thyroid gland, suggested seaweed to help iodine levels
  3. c affect other species, inter-specific effects
  4. d discovery of the second messenger cAMP
  5. e inhibit action of hormones, tamoxifen, and E antagonist in breat tissue

5 Multiple choice questions

  1. largest class, bind polypeptide hormones, neurotransmitters, rhodopsins, odorant molecules, single chain of 7 hydrophobic transmembrane domains separated by hydrophilic segments, receptor when bound to hormone couples to G proteins
  2. tyrosine kinase not part of receptor instead non covalent associated, hormone binding causes formation of dimeric receptor that activates tyrosine kinase in cytoplasm, receptor for GH, prolactin, erythropoietin, cytokines such as interferons
  3. cellular calcium receptor in all eukaryotic cells, four ca2+ binding sites, structurally similar to troponin c, biologically activated when calcium binds to at least three of the four calcium binding sites, activates Ca2+ calmoduline-dependent kinase, stimulates ATPase that pumps Ca2+ out of cells or into storage depots (mitochondria and smooth ER), activates myosin light chain kinase in smooth muscle
  4. alpha-GTP activates enzymes, opens ion channels, activation of enzymes and opening of ion channels generates second messengers, pertussis toxin inhibits on reaction only for Gi
  5. transmembrane form as well as soluble form of gyanylate cyclase, cGMP inactivated by cGMP phosphodiesterase
