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 thecertificate 4.What kind of gas is present in the balloon? Writethe equation for this process. Carbonic Acid, CO2+H2O=Hpos+HCO3Neg 5.Why the balloon wasn’t inflated in the presence ofheat? No Yes No No Yes Flask 1: No glucose as food for fermentation to take place. There fore no CO2 is produced. Flask 2: As yeast utilized glucose and prodced CO2 during fermentation. Flask 3: Boiled yeast failed to ferment and resulted in no CO2. Flask 4: No yeast for fermentation to take place resulting in no CO2. Flask 5: Flour is a mixture of complex carbohydrates, yeast took longer time to break flour down into glucose that being used for fermentation. Red Red Red Red
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.
