Read n%20Pyruvate.pdfwhat did you learn?Cellular Respiration (Carbon DioxideProduction) Go to Questions– using the online virtual lab “YeastFermentation”, outline the steps of the procedure.1.Prepare flask one, two, three, four, and five. 3.Test the gasPredictionUnder which experimental condition(s) you’d expectthe balloon to inflate? The flask with the yeast, glucose, and water. Record your observations from the virtualactivity1.Table 1: Are the balloons inflated?
2.Table 2:what was the pH of carbonated water?3.Why did the litmus paper change the color? Is the beaker solution acidic, neutral, or basic? Go tosubmit thecertificate4.What kind of gas is present in the balloon? Writethe equation for this process. Carbonic Acid, CO2+H2O=Hpos+HCO3Neg5.Why the balloon wasn’t inflated in the presence ofheat? NoYesNo NoYesFlask 1: No glucose as food for fermentation to take place. Therefore no CO2 is produced. Flask 2: As yeast utilized glucose andprodced CO2 during fermentation. Flask 3: Boiled yeast failed toferment and resulted in no CO2. Flask 4: No yeast for fermentationto take place resulting in no CO2. Flask 5: Flour is a mixture ofcomplex carbohydrates, yeast took longer time to break flour downinto glucose that being used for fermentation. RedRedRedRed
Boiled yeast does not ferment. Which will notproduce CO2. 6.Suggest two ways to slow down or stop enzymesused in the respiration process. Changing the temperature will slow down reaction. Changing the pH willalso slow down enzymes.
