Please don't start this until we discuss it in class. You can discuss these with other people, but everyone should write their own answers to these questions.

Why would observing how much or whether the balloon inflated help you determine how much cellular respiration the yeast was able to undergo? Explain. This should involve addressing material we covered in class about cellular respiration and refer to which step(s) are producing the gas and what happens in these step(s).

Why did we test the solutions that didn’t have glucose or starch in them (the yeast and water as well as just the water data I gave you)? Explain.

Some groups might have noticed that the yeast and water solution still produced some gas and inflated the balloon a little bit. Why do you think the solution with just yeast and water might produce gas (even if your group’s didn’t)? Think about why you are still able to go through cellular respiration when you wake up even before you eat in the morning.

Which food source (glucose or starch) allowed the yeast to undergo more cellular respiration (refer to the size of the balloons)? Why do you think this was the case? I would look back at the introductory information on the first page of this lab and directly address information/vocabulary from the biomolecules unit and membrane transport unit at the beginning of the year. You need to look at your notes for these units and use a decent amount of vocabulary.
