5 Essay/Short Answer Questions (6 points) 1. The graph below is a recording of a muscle twitch. In the spaces provided, label the periods A, B and C. Then, in the space below, describe the intracellular events which are occurring during each of the labeled phases. A B C A = Latent Period Description of events: The events of excitation-contraction coupling are taking place, leading to the release of Calcium from the SR. B = Period of Contraction Description of events: Crossbridges are cycling and the muscle is producing force. C = Period of Relaxation Description of events: Calcium is being pumped back into the sarcoplasmic reticulum. 5

6 (8 points) 2. Below is a typical force-length graph for skeletal muscle. For each of the major portions of the graph, explain why the force is rising, falling or staying the same in terms of what is happening at the level of the individual sarcomere. A percent of resting length. (Why is the force zero at 60% resting length?) Muscle force is low because of a low number of cross-bridges that can interact. In addition, some crossbridges are attached to the wrong actin filament so are pulling the wrong direction. At 60% of resting length the force is zero because the thin filaments have run into the Z lines and there are not enough active crossbridges to create significant force. B percent of resting length. The overlap of thick and thin filaments is greater than at 60 80% of resting length so muscle force has increased significantly. However, there is still a suboptimal overlap between thick and thin filaments so force is not maximal. C percent of resting length. (Why is the force maximal in this range?) Maximal force is produced by the muscle due to optimum overlap of thick and thin filaments. This sarcomere length corresponds to the normal resting length of the muscle in vivo. Because the largest number of crossbridges are able to produce force with this amount of overlap, the muscle force is maximal. D percent of resting length. (Why is the force zero at 180 percent resting length?) The sarcomere is so long that there is little overlap between thick and thin filaments, so less force is produced. AT 180% of resting length there is no overlap between thick and thin filaments. Thus, muscle force is zero. 6

7 (6 points) 3. Describe the camp second messenger system for hormone action. Begin with hormone/receptor binding and end with phosphorylation of a protein within the cell. In addition to describing the process in words, draw a diagram depicting the process. See your notes for the answer to this question. 7

8 (5 points) The following four questions relate back to Essay Question #3 and second messenger systems. 4. What class of hormone works via the camp second messenger mechanism? Peptides & amines 5. Where in the process described above does amplification occur? Answer: The steps including activation of adenylyl cyclase, the camp dependent protein kinase, etc. 6. Why is amplification important? Answer: It allows the binding of a single hormone molecule to result in the phosphorylation of thousands of proteins within the cell. 7. What TWO classes of hormones do NOT act via second messenger systems? a. Thyroid hormones b. Steroid hormones 8
