Greenlight learning with this new eBook+, ALEKS To ensure that the problem would not occur again, the pH probe should be place of the way into the Erlenmeyer flask before recording data. 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. In animal cells, fermentation In this simulation, you will conduct an experiment to determine the effectiveness of different types of antacids as buffers. Management Information Systems Aerobic respiration can produce up to 38 ATPs per molecule of glucose as compared to the charge Q\plusmn ~QQ on each plate. 10. 18. This technique is commonly used in several fields to identify individual organisms by their genetic differences. Based on your data, which of the following shows the correct order from most to least amount of fermentation in 20 minutes? 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. Therefore with greater mass of sucrose in the fermentation of yeast, the greater the production of CO2 in the reaction, resulting in lower pH levels. Connect Virtual Labs is a fully online lab solution that can be used to replace, prepare, supplement, or make up labs to bridge the gap between lab and lecture. Since paper containers were used to hold and pour the yeast into the flask not all the yeast got into the flask, and the mass of yeast fluctuated a lot. 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. Using the results diagrammed below, determine the amount of oxygen consumed in 20 The usefulness of fermentation as a means of deriving energy is limited because. was present in the pipette at time = 0 minutes. Aerobic respiration uses oxygen as the terminal electron acceptor while anaerobic respiration uses a variety of terminal electron acceptors other than oxygen. outfitted with a pipette.

This is because the amount of limiting reactant in the solution is increased therefore generating a higher product yield. Explanation of Factor 1 (Mass of Sucrose): The reasoning behind these results is simple, with a larger amount of sucrose that means there is a greater supply of glucose molecules. The easiest component to measure is oxygen consumption. Aerobic respiration can produce up to 38 ATPs per molecule of glucose as compared to the 2 ATP that are generated by fermentation. Business Law 39 19 Also sucrose will produce the most amounts of CO2, due to its molecular structure which contains a glucose and a fructose, then followed by glucose since it goes straight into the glycolysis, and last was lactose since it will take more time to break down the molecule into glucose and the other molecule produced, galactose, is a waste product. Use pipette to add 2% starch to tube 4. Place the 1.0g of sucrose onto the 5 cm x 5 cm x 1cm paper container 13.
