Computer & Information Technology In bacteria and animal cells, the products of glycolysis undergo fermentation in the cytoplasm to produce lactic acid when the oxygen level is low. Fermentation starts with a process called glycolysis. Place both the Lab Quest and pH probe in their respective box. Web. If the living organism is placed in a closed system with the carbon dioxide removed as it is produced, then the consumption of oxygen can be determined using a respirometer.

The amount of sugar will greatly affect the yeast fermentation process because with less sucrose there will be a short supply of glucose molecules for the yeast to ferment with and as a result pH levels will not drop as much due to less CO2 being production. display: none; This yields 2 ATP and 2 NADH molecules which both play a key role for processes that require energy. N.p., n.d. The time that the beans were in the test tube. Pour 100 mL of 40C water into a graduated cylinder. It has no sugar, so it is an experimental control Four test tubes labeled 1-4 were filled with varying amounts of deionized water, yeast, and glucose, as detailed in Table 1, then covered with parafilm.
