These are unable to tolerate even a trace of oxygen. Anthropology
Therefore with a greater mass of sucrose, it results in longer amount of time in which CO2 is being released, in which pH also drops. (ml O 2 /hr) would you predict would happen to the rate of cellular respiration in the germinating Virtual Labs on Frontiers in Biochemistry. Philosophy and Religion

Water, To determine the rate of fermentation, I will measure the hight of the CO2 bubble produced. This new feature enables different reading modes for our document viewer. consumed can be measured over time to calculate the rate of cellular respiration and Also examining the final pHs of each of the sugars, glucose had a pH of 6.09, sucrose had a pH of 5.79 and lactose had a pH of 6.51, and this further proves that sucrose was the most efficient in producing ethanol through yeast fermentation. 0000006580 00000 n

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.
