Ignore the use of glass beads in the video, we dont use those in this lab activity. 16. display: none; As seen in the graph with a greater mass of sucrose, more CO2 was produced, and this is a result of more sucrose being available for the enzymes involved in fermentation reaction to breakdown into glucose and fructose. Connect Master Please provide your instructor a copy of the Memorandum of Accommodation (MOA) from NVCC Disability Support Services. The experiment is easy to carry out, does not require expensive equipment and is suitable for introductory chemistry courses.

Chemistry The overall equation of cellular respiration in most cells is: We can measure the rate of cellular respiration by measuring the consumption of the reactants (glucose or oxygen), or by measuring the rate of production of the end products (carbon dioxide or water) of this process. Lavoisier found that when he added the sugar to the reaction two-thirds of the sugar ended up producing alcohol and the other third was oxidized and became waste in the form of CO2 (This is why there is foam produced on top of most beers). In this paper, we present a simple experiment involving the yeast-catalyzed fermentation of sugars.
