Students have asked these similar questions

A _____________ is a bundle of muscle fibers and is surrounded by connective tissue called ______________.

Part Two: The rest of the story calcium to spill into the cytoplasm of the muscle cell _____ _____ _____ _____ _____ _____ _____ _____ Myosin head un-ratchets and is left holding ADP. As calcium levels in the cytoplasm decrease, there is less calcium to bind troponin and troponin begins to return to its original shape, thus allowing tropomyosin to again cover the actin binding sites. As long as Actin binding sites are available (and there is ATP available) myosin and actin interaction continues ATP ‘attaches’ to myosin head, and (via ATP hydrolysis) the energy released allows the myosin head to release the Actin. Myosin drops the ADP and binds to actin. The free calcium binds to troponin causing the troponin to change shape. Myosin heads ratchet, pulling actin towards the M-line. Troponin’s conformational change (shape change) pulls the tropomyosin off of actin’s binding sites.

A smooth, sustained contraction from rapid stimulation of skeletal muscle fibers is called ________.
