| 19 Muscle: Energy Metabolism and Contraction
|
After reading this chapter you should be able to:
- Compare and contrast the structure, function and metabolism of skeletal, cardiac and smooth muscle.
- Describe the components of the sarcomere in skeletal muscle including the banding pattern and how these change during contraction.
- Outline the mechanisms of mechanochemical coupling and contraction in skeletal muscle, including the roles of Ca2+, ATP, actin and myosin, as described by the sliding filament model.
- Compare substrate utilization for ATP synthesis during short-term high-intensity and long-term low-intensity skeletal muscle contractions.
