Across
  1. 2. maintenance of blood glucose through gluconeogenesis and indirectly via fat breakdown and mobilization
  2. 7. new glucose molecule can enter circulation and be used by skeletal muscle in a cyclic manner
  3. 11. It is released by motor neurons at neuromuscular junctions
  4. 12. increases with exercise levels and may be influenced by menstrual phase
  5. 15. increases with long-duration exercise
  6. 16. the circulating concentrations of epinephrine and norepinephrine increase during exercise according to density and duration.
  7. 17. At which of the following activities would the percentage of total energy expended from fat oxidation be highest?
Down
  1. 1. a motor neuron plus all of the muscle fibers it innervated
  2. 3. loss of muscle tissue as a natural part of the aging process.
  3. 4. a type of muscle cell
  4. 5. helps regulate fluid and electrolyte balance as well as blood pressure
  5. 6. which organ is where glucose is created then it can circulate back to muscle and be used as fuel
  6. 8. an effective ergogenic nutrition supplement when consumed in low to moderate doses
  7. 9. a cyclic operation from the skeletal muscle amino acid pool as well as from the catabolism and muscle protein and transamination occurs.
  8. 10. after excessive sweating and improper fluid balance can lead to
  9. 13. increase is relative to exercise stress; might abate during consistent training
  10. 14. decreases during exercise at high intensity due to alpha adrenergic inhibition insulin release from pancreas
  11. 18. contraction of skeletal muscle cells is powered by
