- Did you notice any changes in the amount of time you could perform each wall sit, or how your legs felt after each of the trials?
- Explain the actions that were occurring at the molecular level to produce this movement. Include sources of energy and any possible effect of muscle fatigue.
- Hypothesize what would happen if blood flow was restricted to the leg when this experiment is performed.
- How do banding patterns change when a muscle contracts?
- What is the difference between a muscle organ, a muscle fiber, myofibril and a myofilament?
- Outline the molecular mechanism for skeletal muscle contraction. At what point is ATP used and why?
