A few hours after the death of an animal, the corpse will stiffen as a result of
continued contraction of muscle tissue (this state is called rigor mortis). This
phenomenon is the result of the loss of ATP production in muscle tissue.
(a) Consult Figure 7.48 and describe, in terms of the six-step model of mus-
de contraction, how a lack of ATP in sarcomeres would result in rigor
mortis.
(b) The Ca* transporter in sarcomeres that keeps the [Ca*)-10-7 M
requires ATP to drive transport of Ca* ions across the membrane of the
sarcoplasmic reticulum. How would a loss of this Ca* transport func-
tion result in the initiation of rigor mortis?
(c) Rigor mortis is maximal at - 12 hrs after death, and by 72 hrs is no longer
observed. Propose an explanation for the disappearance of rigor mortis
after 12 hrs.
Marathon runners often practice "carb loading" prior to a race. The purpose of this practice is to increase the stores of energy available for muscles to use. Explain how energy is used by muscle fibers and how this practice of "card loading" benefits the runner's muscles. Be sure to use the terms glucose, glycogen, creatine, phosphate, and ATP in the explanation.
The filaments of skeletal muscle are moved by free energy derived from the hydrolysis of ATP. During sustained muscle contraction ATP levels remain fairly constant, while levels of creatine phosphate fall. Explain why this is so. Under what circumstances is an oxygen debt incurred during muscle contraction?

- For a skeletal muscle to remain rigidly contracted, it needs a continual supply of ATP. Yet, when a skeletal muscle runs out of ATP (in a corpse), it becomes rigid. How can you explain this seeming paradox? Explain how skeletal muscle may remain relaxed even if ATP levels are high.arrow_forwardDescribe the two mechanisms by which muscle glycogen is broken down to glucose (glycogenolysis) for use in glycolysis.
