Hamsters Love to Run on Exercise Wheels

question 60

Multiple Choice

Hamsters love to run on exercise wheels.Prolonged running at a high rate of speed requires ATP.Could a hamster with a defective gene for the enzyme lactate dehydrogenase meet the extra ATP demand for prolonged,fast wheel-running by maintaining a high rate of glycolysis when muscles are operating under anaerobic conditions? Why or why not?

• A)No,not enough NAD+ can be regenerated for glycolysis to continue at a high rate.
• B)No,the defective gene will cause a rapid decline in pH in the muscles used for running.
• C)Yes,the defective enzyme has no effect on the glycolytic pathway.
• D)Yes,the enzyme alcohol dehydrogenase will supply the needed NAD+ if the lactose dehydrogenase cannot.
