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. Web. How to use a respirometer to measure fermentation, Use a ruler to measure the size of the gas bubble on top of the yeast solution. Since the sucrose will now produce twice as many pyruvate molecules which are later converted to ethanol, this means twice as much CO2 is produced, as a result lower pH levels. Background:___________________________________________________________. Alcoholic fermentation is a common reaction carried out in a wide range of settings from homes for baking bread to factories for brewing beer.
