You are curious to know whether the amount of sugar (food) provided to yeast impacts how much waste gas is produced. To help answer this question, you set up an experiment similar to the one you performed in lab. However, this time, you use four flasks instead of two. In Flask 1 you add 1/4 teaspoon of sugar, in Flask 2 you add 1/2 teaspoon of sugar, in Flask 3 you add 1 teaspoon of sugar, and in Flask 4 you add no sugar. You add 1/2 teaspoon of yeast ("unlabeled sample") and 20 mL of lukewarm water to each flask. You place a balloon on top of each flask. After 30 minutes, you measure the circumference of each balloon to determine how much gas was produced efer back to this experiment to answer questions 1-7. ________________ A) What were the treatment groups in this experiment? B) Which group was the control group?

The data are plotted and we see this graph: 1 2 3 Time (weeks) Yeast A 0% Yeast A 5% Yeast A 10% Yeast B O% Yeast B 5% Yeast B 10% 4. Based on the graph above, which type of yeast is most effective at producing alcohol? Did you expect this - why or why not? (2) % ABV
You are hired by a beer company to optimize their assembly line. They have vials containing a special yeast strain, strain G94, that they simply add to their fermentation tanks. If the generation time of G94 is 25 minutes, how many cells should be inside the vials if they want a fermentation tank to have 100,000 cells after 5 hours? Show your solution.
On the last page of the document I've attached a picture of the data collected. You can see five values (height of bubbles in mm) in each box. That is because my class was divided into five groups that each collected that data. The results become more valid when the data from multiple groups is averaged.
In a reproduction of an experiment famously performed by Louis Pasteur, you cultured yeast in the absence of oxygen (anaerobic growth) and measured (1) the rate of cell division, (2) the rate of glucose consumption, and (3) the intracellular ATP:ADP ratio. You then moved the cells to an incubator containing normal atmosphere (i.e., 21% oxygen), completed a second set of measurements, and made the following observations: The rate of cell division increased considerably after the addition of oxygen (aerobic growth) Glucose consumption dropped dramatically after the addition of oxygen Intracellular ATP:ADP ratios increased significantly (from 2:1 in the absence of oxygen to 10:1 in the presence of oxygen) Explain how the mitochondria in the yeast contribute to the dramatic drop in glucose utilization and increase in ATP concentrations in the presence of oxygen.
The student used three different 250mL flasks, each with 10g of sugar added to them. In flask one 3g of yeast was added, in flask two 6g of yeast was added, and in flask three 9g of yeast was added. Each flask then received 200mL of warm water and then swirled to mix. A balloon was placed over the mouth of each flask to capture the CO2 produced. After waiting for one hour the student measured the circumference of the balloons and found the following: Flask one had a circumference of 10cm, flask two had a circumference of 14cm, and flask three had a circumference of 22cm. What is the purpose of this investigation?

Cathy placed a sample of yeast, a single-celled eukaryote, in a closed test tube containing a solution of glucose. How will the composition of the air in the test tube change as the yeast interacts with the glucose?
In order to have a well-designed experiment, why would it be important to include the beaker of yeast and water.
Yeast is a facultative anaerobe. This means that alcohol fermentation takes place only if: a. the temperature is close to 37°C b. the atmosphere does not contain oxygen c. sugar is provided to the cells d. light is provided to the cells
Fluconazole is used to treat yeast infections by inhibiting the production of ergosterol. What would happen if you took away the ability for the yeast to produce ergosterol?
