  2. Hormone
  3. cyclin adenosine monophosphate cAMP second messenger
  4. discovery of hormones
  5. insulin
  1. a hormone-receptor binding increases adenylate cyclase activity, adenylate cyclase converts ATP to cAMP second messenger, cAMP activates cAMP-dependent protein kinase PKA, PKA phosphorylates proteins
  2. b lowers concentration of glucose in blood
  3. c chinese discovered goiters due to enlarged thyroid gland, suggested seaweed to help iodine levels
  4. d acetylcholine, dopamine, serotonin
  5. e chemical messenger produced by endocrine glands or cells where they affect the activity of these cells

  3. raises the concentration of glucose in the blood

  5. most endocrine glands secrete more than one hormone, placenta is a transient endocrine gland in females, thymus gland atrophies prior to puberty in both sexes

5 True/False questions

  1. calmodulincellular 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


  2. kariomonerecipient benefits


  3. Hippocratesincrease smooth-muscle contraction, blood vessel permeability, and mucosus secretion in airways, synthesized and released by leukocytes, components of inflamatory response
