Biology - Lab Journal - Yeast Metabolism

We ran an experiment where we allowed yeast to consume sugar at 3 different temperatures: 25C, 30C, and 35C. We then measured the increase in CO2 over time because CO2 is a product of yeast metabolism. The three curves are shown below.

Write a lab report with the follow components:

1. Identify the question we are trying to answer using the format "Effect of X on Y."
2. Identify the independent and dependent variables.
3. Describe the results by comparing each of the three curves.
4. Explain a reason for why the 25C and 30C curves come together at 70 minutes.
5. Explain a reason for why the 35C curve has the steepest slope at the beginning.
6. Explain a reason for why all three curves flatten over time.
