Investigation: Muscle Fatigue & Anaerobic Respiration Pre-Lab Questions

1. Describe some situations when we are unable to maintain or supply the demand for oxygen to certain muscles. Answers will vary.

2a. Write the chemical equation for aerobic respiration. C6H12O6 + 6O2 --> 6H2O + 6CO2 + Energy (38 ATP)

2b. Write the chemical equation for anaerobic respiration (lactic acid fermentation). C6H12O6 --> 2C3H6O3+2ATP

2c) How much more energy does the aerobic respiration produce? 19X more

2d) How are the reactants for cellular respiration delivered to the cell? The respiration reactants are carried in the blood stream by red blood cells which exchange respiratory reactants with cells through diffusion.

Investigation: Muscle Fatigue & Anaerobic Respiration Investigation Questions

1. What happened to your “strength” as you progressed through each trial? It decreased.

2. Describe how your hand & fingers felt at the end of your trials. Sore, tired, achy, etc.

3. What is the relationship between your ability to do work with your muscles & anaerobic respiration? As anaerobic respiration increases (O2 levels decrease) , the ability of your muscles to do work decreases.

4. What physiological factors might cause someone else to get more squeezes? stronger heart, better blood flow, increased number of red blood cells, better muscle tone, etc.

Yes (usually). Answers will vary. 5. Were your results different for the dominant hand & non-dominant hand? Explain why they would be different. Yes (usually). Answers will vary.

6. Your muscles would probably recover enough after 10 minutes to operate at the original efficiency. Explain why. After 10 minutes, muscles have rested & oxygen levels supplied to the cells has returned to normal.

glycolysis + anaerobic respiration = lactic acid + 2 ATP 7. Explain how the products of anaerobic respiration cause your cells to be less efficient. glycolysis + anaerobic respiration = lactic acid + 2 ATP glycolysis + aerobic respiration = CO2 + H2O + 38 ATP

8. What is the relationship between the strength of your heart, & aerobic respiration? A strong heart will efficiently move blood throughout the body, allowing nutrients & oxygen to be delivered to the cells.
