Contraction of both skeletal and smooth muscle is triggered by an increase in cytosolic Ca2+. Compare the mechanisms by which each type of muscle converts a rise in Ca2+ concentration into contraction.
A fatigued muscle lacks sufficient oxygen for the aerobic respiration to supply needed ATP. The accumulation of Select one: a. acetic acid occurs and contractions occur with less strength b. lactic acid (lactate) occurs and muscle cramps may set in c. pyruvate occurs and muscle cramps set in d. ethyl alcohol occurs and less frequent contractions occur
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.
Weight training causes fast glycolytic fibers to hypertrophy (increase in diameter). Explain why this increases strength.
How do muscles convert the chemical energy of ATP into force and movement during a contraction?
When Eric returned from jogging, he was breathing heavily, sweating profusely, and complained that his legs ached and felt weak. His wife poured him a sports drink and urged him to take it easy until he could “catch his breath.” On the basis of what you have learned about muscle energy metabolism, respond to the following questions: Why is Eric breathing heavily? Which ATP-generating pathway have his working muscles been using that makes him breathless? What metabolic products might account for his sore muscles and muscle weakness?

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.
