Considering the Length-Tension Relationship of skeletal muscle fibers, over stretching a muscle fiber or not stretching a muscle fiber enough, results ina decrease in force developed (during contraction) because: 27. A. An "over-stretched" muscle fiber or an “under-stretched" muscle fiber will not allow Calcium, from the sarcoplasmic reticulum, to adequately diffuse into the cytoplasm. B. An "over-stretched" muscle fiber or an "under-stretched" muscle fiber will not allow an optimum amount of contact and overlap for the contractile proteins. C. An "over-stretched" muscle fiber or an“under-stretched" muscle fiber will not allow the Action Potential to reach the troponin-activation channels. D.

Discuss the advantages and disadvantages of each of the following types of strength measurement: variable resistance.
Troponin C has been mutated such that it cannot bind to calcium. Describe the effect of this mutation on sarcomere shortening in skeletal muscle. A complete answer will describe the normal function of troponin C, the normal process of sarcomere shortening, and will describe the overall effect of the mutation on sarcomere shortening based on troponin C's function and its role in the overall process of sarcomere shortening.

Describe in detail the events at the neuromuscular junction and how these events allow for the excitation-contraction coupling event to occur. Be sure to also include in detail all the steps at the NMJ and the steps of the excitation-contraction coupling event, including the cross bridge cycle.
Certain multi-headed myosins bind cooperatively to actin filaments. The binding interaction is mainly electrostatic in nature, so the presence of additional salt (ions) in solution can interfere with binding; ions will tend to associate with charged residues on the two proteins, blocking electrostatic attractions that would otherwise take place. Briefly describe the expected shape of the binding curve for one of these myosins, and what will happen to the shape when the salt concentration increases.
