Question
Chapter 7, Problem 10TY
Summary Introduction
Introduction: Under normal conditions, pyruvate undergoes further oxidation for yielding energy, but when the conditions in muscles become anaerobic due to a lot of strenuous activity, oxidation of pyruvate does not occur. Instead, pyruvate is converted to lactate by lactate dehydrogenase enzyme.

- Fast-twitch muscle fibers have fewer mitochondria and less myoglobin to store oxygen than slow-twitch muscle fibers. Use this information to predict how energy production differs in these two types of muscle fibers. Fast-twitch fibers rely primarily on aerobic respiration whereas slow- twitch fibers rely on anaerobic respiration. Slow-twitch fibers are able to produce more ATP per glucose molecule than fast-twitch fibers. You would expect to find more lactic acid build-up in slow-twitch fibers rather than fast-twitch fibers. A & C all of the abovearrow_forwardWhich of the two set ups shall generate higher amount of energy in terms of net ATP generated? Set up A. The one containing 1 mole of trimyristin being catabolized and completely oxidized. Set up B. The one containing combined fatty acids (1mole each) that comprise trymiristin.arrow_forwardWhich of the following statements is (are) accurate about aerobic and anaerobic respiration?a. Aerobic respiration is best for sprints.b. Anaerobic respiration is best for long distances because it does not need large amounts of oxygen.c. Aerobic respiration is faster.d. Aerobic respiration produces more energy per glucose molecule.e. Both aerobic respiration and anaerobic respiration start with glycolysis.arrow_forward
- Muscle soreness and fatigue in a racehorse after a long, strenuous race is a result of in the muscle. A. anaerobic metabolism, which leads to lactic acid buildup B. aerobic metabolism, which leads to buildup of carbon dioxide C. aerobic metabolism, which leads to lactic acid deficiency D. anaerobic metabolism, which leads to ATP builduparrow_forwardAn athlete participates in aerobic exercise three times a week.
