The inconsistent swirling caused the results of the pH to be inconsistent with the trend line and resulted in bad readings. As oxygen is consumed by the organisms, water will start to enter the pipettes. Why does the procedure ask you to dispose of the pipette with each solution? Glucose is a monosaccharide and is used in the first step of glycolysis in order to help create pyruvates, which are then used to create ethanol as long as there is no mitochondria or oxygen present. }

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. N.p., n.d. This lab provides an easy, visual method for determining the rate of fermentation changes as a function of sugar concentration. In this simulation, you will perform a urinalysis of three samples of urine using the dipstick method.

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. Remove storage solution from the pH probe. Raise the clamp with the pH probe and remove the beaker from underneath, and pour the water out into the sink. In fermentation, the electrons are recycled via the NAD+/NADH coupling and ATP is produced only by substrate level phosphorylation.
