} With greater mass of Sucrose results in a prolonged period of time in which the sucrose is being continually broken down, were as with a lower mass of sucrose results in a shorter period of time in which the sucrose is being converted to ethanol. In order to determine the CO2 production rate, the amount of CO2 evolved in each tube was measured from its starting point in 2 minute intervals for 20 minutes. This error could be fixed by consistently measuring the temperature of the water to make sure that they are all same in order to get fair results. 0000001159 00000 n In this simulation, you will find the nearest point at which two patients can still view objects clearly. Tube 4 produced the highest amount of CO2 because it contained the most yeast in combination with glucose. Therefore with greater mass of sucrose in the fermentation of yeast, the greater the production of CO2 in the reaction, resulting in lower pH levels. In this simulation, you will investigate how the digestive enzyme amylase depends on pH for its activity. Cross), Chemistry: The Central Science (Theodore E. Brown; H. Eugene H LeMay; Bruce E.
