For this question you will need to plot the following data on a graph. Simply use a blank sheet of paper, draw an x- and a y-axis, label the x-axis as "sarcomere length" increasing from the origin to the right, and the y-axis as "tension" increasing from the origin up. The units for this graph are arbitrary and for simplicity can be from 0 to 5 units on both axes. Please begin by plotting the following points on your graph: point A at (1,0); point B at (2,1); point C at (3,2); point D at (4,3); point E at (5,0). For those of you rusty in mathematics, the first coordinate in the series is the position left to right (x) and the second number is the position up or down (y). For example, your first point, A, lies on the x-axis (since y=0) and just over 1 unit (since x=1). Your newly drawn graph depicts the sarcomere length-tension relationship in the average skeletal muscle. Now answer the following questions: Why is it that the sarcomere exerts maximum tension at point D on your graph? Why is it that the sarcomere exerts no tension at point A? Why no tension at E?
