You're taking a train from Istanbul to Zagreb, and there has been a murder! Fortunately, a world-class detective is on the train with you and the train's owner ask him take over the case. You are not a suspect, but you are an expert in human physiology. You examine the body for "rigor mortis" to estimate the time of death. Rigor mortis occurs because, at death, all the existing ATP is rapidly depleted and no new ATP is made. The lack of ATP prevents the cross-bridge cycle, and the muscles become extremely stiff. You explain all of this to the detective, Hercule P, but he's confused why the lack of ATP would make the body stiff rather than limp. After all, isn't the primary function of sarcomeres to build tension in muscles? You tell Hercule that the lack of ATP actually prevents:
