Sliding Filament Theory and the Sacromere Practice Problems

If a sarcomere exceeds the ideal length, it will lead to:

What does calmodulin activate, which in turn facilitates the binding of myosin head to actin?

The portion that marks the boundary of the sarcomere which moves closer together during muscle contraction is called:

Which protein covers the active sites of actin in resting muscle fibers?

What is the functional unit of contraction in a muscle fiber that spans from one Z-disc to the next Z-disc?
