WebAug 4, 2024 · When the yeast grows, it produces a gas called carbon dioxide, or CO 2, which you can use measure how yeast grows over time. This experiment uses bottles and balloons to capture the CO 2 from fermenting yeast and helps you to visualize how yeast uses sugar to grow. Part 1 Filling the Bottles 1 WebThe growth rate of a particular yeast is modeled by the differential equation d t d P = k P. Suppose a population of yeast doubles in size every 12 hours.
