    it will diffuse until it reaches equilibrium
  22. Hypertonic
  23. *Higher concentration of solutes outside the 
    •   cell
    • *Water moves out of the cell
    • *Crenate
  24. Isotonic
  25. *Equilibrium
    *No movement
  26. Hypotonic
  27. *lower concentration of solutes outside the
    •   cell
    • *water moves into the cell
    • *hemolyse
  28. Which way will water flow across a membrane?
    High to low concentration
  29. How to solve for molarity and osmolarity
  30. %=Grams/100 ml * 1 mole/58grams * 1000 ml/1 liter = moles/liter *2 if NaCl or 3 if MgCl2
  31. If you place two solutions with different osmolarities into a beaker with a semi-permeable membrane, towards which solution will the water flow, the higher or lower osmolarity solution?
  32. Higher osmolarity
  33. If you place RBC in a solution with a low solute
    the solution will appear clear
  34. Buffers
  35. Buffering has no affect on enzyme activity
  36. 1)       Iodine test
    Is used to detect the presence of starch
  37. Benedict’s test
    Is used to detect the presence of maltose
  38. Sequence of steps in an ELISA
    Antigen, serum, antibody-linked enzyme, substrate
  39. Purpose of the enzyme linked to the antibody
    It catalyzes the conversion of a colorless substrate to a colored product
  40. Spatial summation
    increases the number of motor units in muscle contractions
  41. Temporal Summation
    increases the rate of stimulus in muscle contractions
  42. Tentanization
    A steady state of contraction when muscles are stimulated at high frequencies
  43. Four events of a muscle twitch
  44. Stimulus
    • Latent period
    • Contraction
    • Relaxation
  45. How is the release of thyroxine controlled
  46. It is controlled by the pituitary gland which secretes TSH.  This is carried by the blood to the thyroid gland and causes the thyroid to produce more thyroxine.
  47. Catabolism
  48. Breaking up coumpounds
  49. Anabolisim
    generating complex compounds amino acids
  50. Function of estrogen and where it’s produced
  51. Produced in the ovariesEstrogen enables the endometrium of the uterus to grow and develop so that the uterus may receive fertilized eggs for implantation
  52. Function of insulin
  53. It is vital to the regulation of blood glucose levels because it enables the body’s cells to absorb glucose from the bloodstream
  54. Type I Diabetes Mellitus
    body does not make insulin.

    Autoimmune-mediated destruction of insulin producing beta cells in the pancreas resulting in absolute insulin deficiency.
  55. Type II Diabetes Mellitus
    body makes insulin but does not respond to it. it is unable to be absorbed through the cells.
