Although it may take longer to breakdown the sucrose in order to get the glucose molecule it is made up with the fructose, since the fructose is symmetrical it skips a step in glycolysis this means it will be converted to pyruvate quicker than a glucose since it is easier to breakdown. If you increase the temperature of the water bath that the respirometers were in, what Then, fermentation finally occurs in the absence of oxygen, or anaerobic environments.

Yeast is a fungus capable of converting sugars into alcohol and carbon dioxide (CO2) by the process called alcoholic fermentation. Metal Stand with clamp Ethanol fermentation is a system in which hydrogen ions from NADH + H+ are broken down in order to release the trapped energy and regenerate NAD+.
-The experiment needs a control so you can be sure that fermentation does not occur without sugars. why?

Fermentation can be difficult to measure in animal cells, so yeast is often used to observe the results of this process. 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. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). has entered the pipette at time = 20 minutes and subtracting the amount of water that oxidative phosphorylation. Therefore according to the results of the graph sucrose fermented yeast the most efficiently, then glucose and finally lactose. }
