- In the second experiment, you perform everything the same wayyou did in the first, but this time you replace the air in eachflask with nitrogen gas (N2) which is essentially inertbefore you begin. Graph the data, and be sure to display theequations of the trendlines for each condition. Insert your graphbelow the data table and answer the following questions.

a) How does the rate of glucose consumption compare with thefirst experiment you did?
b) Do you think yeast is performing cellular respiration? Why orwhy not.
