Across
  1. 2. rate of fatigue of slow oxidative muscle fibres
  2. 3. rod-shaped protein, blocks the active sites for myosin on actin by spiralling around actin
  3. 9. globular structure, keeps tropomyosin over active sites on actin, binds to calcium when muscle contracts
  4. 10. energy source for direct phosphorylation
  5. 12. type of contraction that occurs when the muscle lengthens
  6. 13. type of muscular contraction where there is no change in length
  7. 15. glucose is the energy source for this pathway, does NOT require oxygen
  8. 16. thin filament
  9. 17. number (full word) of seconds direct phosphorylation provides energy for
Down
  1. 1. type of contraction that occurs when the muscle shortens in length
  2. 2. muscle fibre types used for endurance activities
  3. 4. region of a myofibril between two successive Z discs, functional unit of skeletal muscle
  4. 5. red pigment that stores oxygen, similar to hemoglobin
  5. 6. muscle fibre type with intermediate glycogen stores
  6. 7. site of ATP formation for aerobic cellular respiration
  7. 8. colour of fast glycolytic muscle fibres
  8. 11. plasma membrane of skeletal muscle fibres
  9. 14. thick filament
  10. 18. structure formed by a T tubule with the terminal cisterna on either side
