Student V and student W wanted to do metabolism experiments with student V doing a fermentation experiment and student W doing an aerobic respiration experiment. Student W used 6 test tubes with balloons tied to the top of each test tube, but in each test tube student W put germinated beans. Student W used the same temperatures as student V. After 45 minutes, student W noted that there was no inflation of any balloon. Why did this happen?

Solved in 3 steps
- Student V and student W wanted to do metabolism experiments with student V doing a fermentation experiment and student W doing an aerobic respiration experiment. Student V put yeast, sucrose, and water in 6 test tubes with balloons tied to the top of each test tube (to capture any gas given off) and put the test tubes in water baths at the following temperatures (in degrees Centigrade): 0, 20, 30, 40, 50, and 100. After 45 minutes, student V noted that there was no inflation of the balloon in the first tube, a little in the second tube, and then an increasing amount of inflation until the last tube in which there was no inflation. Explain the results of Student V’s experiment.water and yeast water, yeast, and sugar water and sugar water, yeast and flour boiling water, yeast and sugar which balloons did fermentation occur? In which balloon did the most fermentation occur and why? Of the balloons in which fermentation occurred, which balloon emitted the smallest amount of carbon dioxide gas (less fermentation occurred). Discuss why this happened List the balloons in which fermentation did not occur, and discuss why fermentation did not occur in each.What is the difference between Fermentation and Respiration .
- What causes the suction on your thumb after the NaOH was added to the contents of the fermentation tube? Write two balanced chemical equations to support your answer describing the reactions that occur between the entrapped gas and NaOH.What molecules from the cellular respiration reaction could be used in the experiment to then calculate the rate of cellular respiration? C_6H_12O_6 O_2 CO_2 H_2O Energy1st Bag: shredded wheat original cereal, Warm water, and yeast (no sugar) 2nd Bag: Cinamon Toast Crunch, Warm Water, and yeast 3rd Bag: Fruit Loops, Warm Water, and yeast (all these bags were placed under a heat lamp for 25 minutes) (After these bags were placed under the heat lamp and they all had different reactions after put under the heat lamp, due to the sugar contents in the cereals) So the question is: The sugar content was higher in some bags than others. What did you observe in the bags containing more sugar?
- One cycle of fermentation yields more energy than one cycle of aerobic respiration.True or false?In one final experiment, you add all the necessary components and program the thermocycler to cycle under the following temperatures Denaturation 95 degrees, 30 seconds, Annealing 65 degrees, 30 seconds, Elongation 68 degrees 30 seconds You find out that the third time's the charm, but now you have many small incomplete fragments instead. What happened and how did you fix it?What is the difference between alcoholic fermentation and cellular respiration? Cellular respiration requires oxygen and alcoholic fermentation does not Alcoholic fermentation requires oxygen and cellular respiration does not Cellular respiration requires carbon dioxide and alcoholic fermentation does not Cellular respiration produces carbon dioxide and alcoholic fermentation does not
- What happens if initial temperature is not recorded in the experimentIn this lab, we used three different bacteria (E.Coli, B. Subtilis, and A. Faecalis) in fermentation assays to determine their ability to ferment three different carbohydrates: lactose, glucose and sucrose. In the table below record the results of the experiment using "P" for positive and "N" for negative results.How can we conduct an experiemnt in peas to support a hypothesis about the relationship between temperature and the rate of cellular respiration? what can we expect about the results?
