Interested in studying ethanol fermentation, you prepare two solutions of yeast extract that contains the cytosolic contents of Saccharomyces cerevisiae. You add glucose to both extracts at time zero, but to one (in red) you also add inorganic phosphate (added in two batches). Using a gas sensor, you monitor the CO2 generated by the two solutions over time and obtain the following data:
