Indole production test: Bacteria is grown in the peptone water culture. After 48 to 96hrs, incubation at 37°C, it is checked for the presence of red color. Purpose of the Lab In this lab, you will try to determine whether yeast are capable of metabolizing a variety of sugars. When yeast respire aerobically, oxygen gas is consumed and carbon dioxide, C0 2, is produced. You will use a C0 2 Gas Sensor to monitor the production of carbon dioxide as yeast respire using different sugars.

The solution in Figure 12.1.1 contains 10.0 g of cobalt(II) chloride dihydrate, CoCl 2 ·2H 2 O, in enough ANS: A quick internet search will return the answer. Phenolphthalein is colorless in solutions where the pH is below 8.2, but pink to purple in solutions with a higher pH. A perfectly neutral solution has a pH of 7.0. Therefore, the solution will require slightly more NaOH to reach the titration endpoint then necessary to become perfectly ... 4. What is the optimum pH level for this enzyme? How do you know? Make a prediction about what you think the reaction rate would look like a pH = 2. 5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate.
