Cellular Respiration lab Data Table and questionsName______

Observations just yeast / Observations yeast and water / Observations yeast and apple juice
Original
After 1 day
After 2 days
After 3 days

Questions

  1. What was the dependent variable in this experiment?
  2. What was the dependent variable?
  3. What were the constants in this experiment?
  4. How could Mr. Scanlon have changed the experiment to be better experiement?
  5. Did the balloons change in circumference during the period of this experiment? If so, how did they change? What specifically accounted for the changes if they occurred in this experiment?
  6. What was the specific source of energy in the apple juice the yeast used for respiration?
  7. How would changes in room temperature influence this investigation? Explain why in terms of your knowledge of reaction rates and respiratory enzyme function.
  8. How did the physical evidence collected in this investigation support the hypothesis that yeast carry on respiration?
  9. The yeast began its respiration aerobically, but then after time completed it anaerobically. How do these two processes differ in terms of the productsand energy yielded in this process? List two in which the two respiration processes are similar?
  10. What very important cellular process had to take place BEFORE cellular respiration in order for this experiment to have happened?(HINT: What important ingredients did we have to put in the flask that worked?)
  11. How are cellular respiration and photosynthesis similar? How are they different?
