Question
Chapter 50.4, Problem 5R
Summary Introduction
To review:
The mechanism by, which pyruvate and lactate support continuing glycolysis.
Introduction:
Muscles do not get enough oxygen when the person is exercising. In this situation, the muscles produce pyruvate and lactate in addition to small amounts of adenosine triphosphate (ATP). The pyruvate and lactate produced in the muscles can be again utilized in glycolysis.

Trace the fate of hydrogens removed from glucose during glycolysis when oxygen is present in muscle cells; compare this to the fate of hydrogens removed from glucose when the amount of available oxygen is insufficient to support aerobic respiration.
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.
Explain how production of lactate from pyruvate can promote glycolysis in the muscle cells

- As early as the 1930s, it was known that frog muscles could still contract when glycolysis was inhibited. Where did the ATP come from to drive these contractions?arrow_forwardFast-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.

- Select the correct answer: Lactate dehydrogenase (LDH) plays an essential role in an exercising muscle, especially when the level of excursion surpasses the ability of circulatory systems ability to supply adequate oxygen. What is the main reason LDH is so important to the muscle under these conditions? A)It removes excess lactic acid from the muscle to create pyruvate. B)It produces NADH for energy while converting pyruvate into lactate. C)It resupplies NAD+ to glyceraldehyde 3-phosphate dehydrogenase. D)It decreases pH thus decreasing the dissociation rate of oxygen from hemoglobin. E)It produces one mole of ATP via substrate level phosphorylation.arrow_forwardAssuming that all the glucose entering a muscle fiber is oxidized, as what molecule will the glucose carbon leave the body? Of glucose’s six carbons, two oxidized carbon byproducts will be produced by one enzyme, and four will be produced by a metabolic pathway. At which enzyme and pathway are these carbon-based bi-products produced?arrow_forwardThe transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.arrow_forward
