I am needing help with problems 1 and 3, please. Thank you.    1) Yeast uses anaerobic respiration.  If yeast utilized aerobic respiration, would the balloons have inflated faster or slower?  Why? 2) Glycolysis in an anaerobic environment produces a net of 2 ATP and Pyruvate.  Why does Yeast bother to ferment Pyruvate to Ethanol? Also, what do you think would happen if yeast DID NOT ferment pyruvate to ethanol? 3) Glycolysis in an aerobic environment leads to the production of many more ATP biomolecules.  Briefly describe the additional steps necessary to harvest more energy from glucose breakdown.  Include the step where Oxygen is used, since it is the key factor that determines the amount of ATP produced.
