2. Yeast and other organisms can convert glucose (C6H1206) to ethanol (C2H5OH) through a process called alcoholic fermentation. The net reaction is C6H12O6(s)—2 C2H5OH(1) + 2 CO2(g). Calculate the mass of glucose required to produce 1.0 L of CO2 at a pressure of 1.0 atm and temperature 300 K. 0 3.654g 0 180.0 g 05.820g 0 45.0 g

2. Is there a difference between the fermentation rate of the yeast and the top the fermentation rate of the yeast and the temperature? Why? 3. Why do you need to incubate the yeast before you start monitoring air pressure? 4. What else do you think is being produced by yeast fermentation besides CO2? 5. Could you use a pressure sensor to measure aerobic respiration in yeast? Why?
