Question

Question 5: To further analyze the metabolism of yeast you run a trial using glucose as the sugar. You then analyze the chemical composition of the broth that remains in the glucose flask after 300 s. Will the concentration of glucose in this flask have increased, stayed the same, or decreased? Briefly explain your reasoning. (1.5 pts) I Question 6: Given that human cells can metabolize glucose, if you ran a treatment that included cultured human cells instead of yeast cells in glucose broth in the absence of Oz would you expect the gas pressure to increase, decrease, or stay the same? Briefly explain your reasoning. (1.5 pts) Question 7: You now turn your attention to the vines from the vineyard. You analyze the respiratory quotient for a fully saturated fatty acid, myristic acid (CH2,02), which the vines can metabolize in an aerobic environment. a) Show the balanced equation for the metabolism of myristic acid. b) What is the predicted respiratory quotient for the vines as they metabolize myristic acid?

Answer 1

5. Glucose is the main carbon source for yeast for the energy production in yeast. After 300s the amount of glucose will be reduced in the solution. The amount of glucose utilised will be converted into ethanol.
