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