- 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.arrow_forwardWhile the sarcoplasmic reticulum of muscle was first described by nineteenth-century microscopists, its true significance was not ap-preciated until its intricate structure was revealed much later by the electron microscope.

- Skeletal muscle fibres are very metabolically active and are adapted to create a lot of ATP from aerobic cellular respiration. Additionally, cells require other things to stay alive. Explain how the following three organ systems contribute to allowing a muscle cell to carry out its roles: a) Respiratory system b) Cardiovascular system c) Gastrointestinal system asap please.arrow_forwardAs mentioned in class, one additional major use of ATP in skeletal muscle (besides powering the myosin heads) is the recycling of calcium ions back into the sarcoplasmic reticulum after depolarization. The resting concentration of Ca++ in the muscle cell cytoplasm is about 50-100 nM, and the spike concentration after depolarization is about 10-20 μΜ. a) Consider a single sarcomere. What is the number of free calcium ions within the sarcomere at rest? What is the number of free calcium ions after depolarization? b) The major ion pump responsible for calcium ion recycling is SERCA (sarco/endoplasmic reticulum calcium ATPase). SERCA uses one molecule of ATP to pump two calcium ions, and the resting level can be restored in about 10-20 ms. How many molecules of ATP are used in a single sarcomere for pumping calcium in a single "twitch"? c) Assume that a single "twitch" is sufficient to drive one sarcomere from its fully extended length (about 2.5 µm) to its fully contracted length (about 1…arrow_forwardThe ability of myosin to walk along an actin filament may be observed with the aid of an appropriately equipped microscope.
