You and some of your AP Bio classmates decide to take your yeast respiration lab to the next level and research different ways you could do this experiment. You come across one set up that looks like this: a. What type of metabolism is the yeast doing in this experimental setup? *paraffin is a wax)* Explain how you know.

b. You want to mimic bread making, so you decide to put your yeast in a mixture of water and flour instead of a sugar mixture. Flour contains gluten which when can form disulfide bridges in solution. Based on this information, what is gluten and describe how you know?

c. You repeat the experiment with lipids added to the mix. You notice that the rates of metabolism look as follows. Interpret the results and what fats do to yeast metabolic rate.
