4 cards from this section. Quick, good the night before a test.
What are the two main proteins involved in muscle contraction?
Think about the basic building blocks of muscle fibers.
What is the role of calcium in muscle contraction?
Consider what is needed to activate the muscle fibers.
What is the main hypothesis of the sliding filament theory?
Focus on the movement of the filaments.
True or False: The binding of ATP to myosin head is necessary for muscle contraction.
Think about when ATP is utilized in the muscle movement process.
If ATP is depleted in muscle cells, what impact will it have on muscle contraction? Discuss the implications on both the short-term and long-term performance of muscles.
Think about what happens during exhaustion, and relate that to ATP's role.
Design an experiment using isolated muscle fibers to determine how changes in calcium concentration affect muscle contraction strength. Outline the key steps.
Consider the relationship between calcium and the sliding filament theory.
