Passage
Yeast is a unicellular fungus, and is arguably one of the most important members of the fungus family, primarily because of its involvement in the process of fermentation.
During this process, yeast breaks down sucrose into alcohol and carbon dioxide. The chemical equation for fermentation is given below. Scientists study how to induce fermentation in yeast most effectively.
C12H22O11 + H2O → 4C2H5OH + 4CO2
Experiment 1
Since yeast needs sucrose to ferment and molasses is 60% sucrose, scientists first study yeast grown in molasses.
Five test tubes are filled with .4 grams of yeast and various molasses concentrations. Carbon dioxide levels are measured as an indication of fermentation for each test tube after one day and again after two days. These levels are shown in Table 1.

Experiment 2
Five different test tubes are filled with .4 grams of yeast and various pure sucrose dilutions. Carbon dioxide levels are then measured as an indication of fermentation after one and two days. These levels are shown in Table 2.

Experiment 3

Eight more test tubes were filled with .4 grams of yeast and a 15% sucrose solution. Various combinations of ammonium sulfate, potassium dihydrogen phosphate, minerals, and vitamins were added to the test tubes. Carbon dioxide levels were measured after one and two days. These levels are shown in Table 3.
Q. Based on Experiments 1 and 2, one can infer that, as compared to molasses, pure sucrose:
  • a)
    is more effective at inducing fermentation in yeast.
  • b)
    is less effective at inducing fermentation in yeast.
  • c)
    is exactly as effective at inducing fermentation in yeast.
  • d)
    does not induce fermentation in yeast.
Correct answer is option 'A'. Can you explain this answer?

The best answer is A. You are given that CO2 is a by-product of the fermentation process. While Experiment 1 used molasses, Experiment 2 used pure sucrose dilutions, which yielded higher overall CO2 levels in each test tube. The data suggest that pure sucrose is more effective at inducing fermentation in yeast than is molasses.
