  1.  Which of the following energy sources produces ATP at the
      GREATEST rate?
      a. muscle glycogen
      b. liver glycogen
      c. creatine phosphate
      d. blood glucose
      e. adipose triglycerides

  2.  During high-intensity, fatiguing exercise in which
      anaerobic reactions predominate, ___________ is used
      as the primary source of energy.
      a. ketone bodies
      b. muscle glycogen
      c. blood glucose
      d. fatty acids
      e. amino acids

  3.  In the "Central Fatigue Hypothesis", the reduction in plasma
      branch chain amino acids is thought to result in an increase
      in which hormone?
      a. insulin
      b. glucagon
      c. valine
      d. adrenaline
      e. serotonin 

  4.  Caffeine is thought to be an ergogenic aid for endurance athlete 
      because of the effect it has on increasing the activity of:
      a. creatine kinase
      b. neutral amino acid transport proteins
      c. anaerobic glycolysis
      d. electron transport system
      e. adipose hormone sensitive lipase

  5.  "Hitting the wall" or "bonking" refers to :
      a. sprinters as their muscles are in lactic acidosis
      b. a popular sport in bars and taverns
      c. development of ketosis in endurance athletes
      d. depletion of muscle glycogen in endurance athletes
      e. amino acid depletion during heavy weight training

  6.  Which of the following nutrients is required for the transport of
      fatty acids through the mitochondrial membrane for oxidation?
      a. alanine
      b. carnitine
      c. glycogen
      d. coenzyme Q10
      e. ubiquinone

  7.  During the 100 meter dash, more than 70% of energy
      is derived from aerobic metabolism.

  8.  Liver glycogen does not play an important role in exercise energy
      metabolism.

  9.  According to the ACSM consensus paper on creatine use as
      an ergogenic aid, it is essential for creatine to be consumed at 
      a dosage of about 25grams per day for 3-4 days in order for
      a significant elevation in muscle creatine to occur.

 10.  Carnitine may be an ergogenic aid because of the role it plays
      in enhancing glycogen storage.

 11.  Depletion of muscle glycogen concentration is associated with
      higher ratings of perceived exertion.

 12.  During high intensity exercise like weight lifting, protein
      oxidation for energy production contributes about 40% of energy
      needs.
