Another error in this lab would have been the temperature of the water since the waters temperature was not consistently measured, and since the water could have been colder in one of the experiment then the other this could have affected the fermentation because enzymes work better in hotter temperatures and if one is colder than the other this would mean the fermentation could have been less efficient. Swirl the beaker full of water until Lab Quest approximately reaches a pH of 7. How does the new value Also sucrose will produce the most amounts of CO2, due to its molecular structure which contains a glucose and a fructose, then followed by glucose since it goes straight into the glycolysis, and last was lactose since it will take more time to break down the molecule into glucose and the other molecule produced, galactose, is a waste product.
