The given graph shows length-tension curve for a typical vertebrate sarcomere.

By ana lysing the graph, what can you deduce regarding the muscle contraction?
(i) Neither the myosin filaments nor the actin thin filaments change in length when a sarcomere shortens or is stretched. Instead, it is the extent of overlap between actin and myosin filaments that changes.
(ii) The total tension produced by a sarcomere is proportional to the total number of cross-bridges that can interact with actin filaments, and this number in turn is proportional to the amount of overlap between thick and thin filaments.
(iii) The tension produced by the muscle is maximal when the overlap between thick and thin filaments allows the largest number of myosin cross-bridges to bind to actin.
(iv) Tension drops off with increased length, because the thick and thin filaments overlap less and fewer cross-bridges can bind.
(v) Tension drops off with decreased length, because thin filaments at the two ends of the sarcomere begin to collide with each other, preventing further shortening.

(a)
(ii) only

Long distance, competitive runners are usually small and wiry and run more slowly than sprinters, who run much shorter distances and generally have a large bulk of muscles. Which of the following best explains the differences between the two types of runners?

(a)
Long distance runners run more slowly because lactic acid quickly builds up in their muscles and causes fatigue. Sprinters do not run for a long enough for lactic acid to build up in their muscles.
(b)
The large muscles of sprinters increase the oxygen supply to each muscle, preventing lactic acid from forming.
(c)
Sprinters do not run for long enough for sufficient lactic acid to build up in their muscles therefore they can have large muscles for more power. By being lighter and running more slowly long distance runners ensure that their muscles receive enough oxygen for aerobic respiration.
(d)
Sprinters run faster because their large muscles have more blood running through them to stop anaerobic respiration from taking place. Long istance runners run more slowly because they are using the energy from anaerobic respiration, which does not produce as much ATP as aerobic respiration.
