After strenuous exercise, you may notice that your muscles burn and feel sore the next day. Which statement best explains this phenomenon? (a) Proteins in muscle cells are being digested to provide energy. (b) Carbon dioxide is building up in muscle cells and changing their pH. (c) Spontaneous combustion occurs during strenuous exercise, so avoid it at all costs! (d) ATP is accumulating in muscle cells, causing a burning sensation. (e) Without adequate oxygen, muscle cells are fermenting pyruvate into lactic acid.

Which of the following statements correctly describes why white muscle fibers do not need is mini mitochondria as red muscle fibers? a) want muscle fibers use anaerobic respiration which does not occur in the mitochondria b) what muscle fibers use anaerobic respiration which requires more efficient mitochondria than aerobic respiration c) white muscle fibers get more oxygen than the red muscle fibers
You start to run, and your skeletal muscles need to work harder. Which of the following is the immediate source that your muscles use to get the energy they need? A)Glycolysis B) Oxidative phosphorylation C) Creatine phosphate D)Myoglobin
When an animal dies, its limbs and body become stiff because its muscles go into rigor mortis (literally, rigor mortis means “stiffness of death”). Why would the loss of ATP following death cause this to happen?
Which energy system did you use for 5 mins of jogging (around the house or up/down the stairs)? what is the main sourse of energy for ATP replenishment for this system? What is the limitation of this energy sourse? What muscles fibres recruited? A) ATP-PC system B) Glycotic system (Glycolysis - pyruvate) C) Cellular Respiration (Aerobic Respiration - ETC)
Which of the following does NOT happen when your muscles are fatigued? A) Lactic acid buildup causes an increase in ATP production. B) Oxygen to the muscle decreases C) recovery period ‘pays back’ the oxygen debt D) ATP production decreases
6. Which of the following is true of aerobic respiration? A) It involves the reduction of oxygen. B) It involves the oxidation of oxygen. C) It involves the reduction of lactic acid. D) It involves the oxidation of lactic acid. E) It does not generate ATP.
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.

Please answer 1) Which of the following is true concerning creatine phosphate (CP)? a) It can directly be used for energy if ATP is not available. b) It can be used to produce ATP in one step. c) A limitless amount can be stored in cells. d) Relatively large amounts of ATP can be produced from CP.
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?
After finishing a grueling marathon, a runner exclaims, “Whew, I think I’ve used up all my ATP!” Could this be possible?
