Across
- 1. respiration with oxygen
- 4. muscle for involuntary movement
- 5. makes energy for the cell
- 7. Energy made in the mitochondria
- 9. fast muscle contractions and uses aerobic respiration
- 10. respiration without oxygen
- 13. muscle for voluntary movement
- 14. structural proteins are added to muscle fibers
- 15. formation of capillary networks to supply oxygen and remove waste
Down
- 2. muscle fiber contract slowly
- 3. anaerobic respiration
- 6. product of anaerobic respiration and can build up in muscles
- 8. decrease in muscle mass
- 11. muscle that pumps the heart
- 12. muscle atrophy related to age
