Summary Introduction

To analyze:

Fermentation tubes are evaluated at 24 and 48 hours. If an organism used up all carbohydrate in fermentation tube, then what happens and the organism use for energy and the color the indicator shows.

Introduction:

Fermentation is a process that breakdown large and complex sugar into smaller molecules with the help of bacteria and yeast. This process is used to make beer, alcohol, and fermented drinks.

Explanation of Solution

The process occurs in a lack of oxygen known as the anaerobic process as well as produces a significant amount of ATP. Its product is carbon dioxide, lactic acid, and ethanol. The process is very useful in wine as well as beverage industries.

Beer is the product of fermentation that is consumed as an alcoholic beverage. The flavoring of beers is done with hops that usually add bitterness as well as a natural preservative. Fermentation results in natural carbonation within the beer. It contains around four percent to six percent alcohol.

Fermentation can take place without or with the presence of oxygen as well the incubation periods that are prolonged results in the growth of bacteria oxidatively on peptone immediately after consuming the carbohydrate supplied.

A neutralization reaction will take place when an organism will use all the present carbohydrates. The organism will start using peptone as an energy source. The color of the indicator will turn red.

Conclusion

Thus, Fermentation can take place without or with the presence of oxygen as well as the incubation periods that are prolonged results in the growth of bacteria oxidatively on peptone immediately after consuming the carbohydrate supplied.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…
