Question

4. How much is Pi required to generate one CO2?
5. Is CO2 generation the most reliable way to measure ethanol fermentation? Why or why not?

Definition Definition Diverse group of organisms that primarily obtain nutrients through absorption. They range from single-celled yeasts to complex multi-cellular structures such as mushrooms. Fungi play important roles in ecosystems as decomposers, plant symbionts, and even pathogens. They also have practical uses in medicine, food production, and industry.

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. Create a data table that would be used to collect and organize the data from this experiment.

The following four chemicals commonly found in defined growth media contain all of the necessary atomic macronutrients, namely C, O, N, H, S and P, which microbes require: glucose (C6H12O6), K2HPO4, MgSO4.7H2O, and (NH4)HPO4. Part a. Create a simple diagram to map which growth media chemical contributes atoms to which of the four biological macromolecules (amino acids, polysaccharides, lipids, and ribonucleic acids). Part b. Consider a cell culture broth that originally (before inoculation with cells) contains 5.0 gr/L glucose (C6H12O6), 1.2 gr/L K2HPO4, 0.3 gr/L MgSO4∙7H2O, and 1.0 gr/L (NH4)HPO4. Create a table showing how much of each of the different atoms (C, H, O, K, P, Mg, S, N) are available for incorporation into cell macromolecules (assume 50% of the glucose is catabolized, while the remainder goes for energy (respiration). Express your answers with units of grams of atomic species / liter of culture broth.
