Analysis of Factor 2 (Type of Sugar): Analyzing the results of the trend lines from the graphs of the three different types of sugar, the results showed that sucrose produced the most CO2 over the period of time. However, when oxygen is not available, living organisms can still obtain energy by performing fermentation to partially break down glucose to produce 2 ATP molecules from each glucose molecule. Distinguish between anaerobic and aerobic respiration. absence of a terminal electron acceptor, instead fermentation will occur.

The second factor that will be measured in this experiment is the amount of sugar used in yeast fermentation reaction. Sucrose produced co2 the fastest where as glucose and fructose could not produce at such a rapid rate due to their monomer states. Glycolysis, 2) Krebs Cycle (Citric Acid Cycle), and 3) Electron Transport Chain (ETC) and Use pipette to add 2% starch to tube 4. (a) The sample is transferred from one container to a larger one. In conclusion the final results of pH from the lab were as expected in 1.0g having the lowest pH (5.87), 0.5g having the 2nd lowest pH (6.01), and 0.25g had the highest pH (6.18). Therefore sucrose will produce the most CO2 out of the three types of sugars due to its complex structure, then glucose since there is no breakdown needed, finally lactose because it needs to be broken down and it only produces one glucose that can be used in the fermentation reaction. display: none; It is defined as the conversion of glucose into energy, ethanol, and CO2. .image-2x2 { The results are shown in Graph 1. organisms to stay alive, to maintain homeostasis, and run all kinds of life activities. The glucose molecule would go through glycolysis, were the fructose molecule would skip a step and be further broken down to make a pyruvate. 3 sucrose 4mm 25mm 21mm.

Throughout the experiment there were sudden drops and gains in the mean ofthe pH, which could have been cause by the pH probe not put far enough into the Erlenmeyer flask, and when corrected the pH had a sudden drop. Need a custom essay sample written specially to meet your Market-Research - A market research for Lemon Juice and Shake. display: none; In this simulation, you will place sketches of the different phases of meiosis I and meiosis II in the correct order and label them, match micrographs of cells undergoing meiosis to the correct phase name, and look at microscope slides of cells in an ovary and testis and identify germ-line cells and structures. In this simulation you will identify the proper instruments for performing an eye dissection, identify the required steps to complete an eye dissection, perform a coronal cut of a cow eye and identify the gross anatomy observed during an eye dissection. A possible explanation could be that upon pouring yeast into all of the tubes, the tip of the graduated cylinder being used was contaminated with glucose from other tubes. 0000001315 00000 n Accounting Turn off Lab quest. The three major parts of aerobic respiration are 1) Exercise 3 - Design an experiment. comparison between supplementation of yeast and MFL in a concentrate diet by using an in vitro gas production technique, it was found that the in vitro dry matter degradability (IVDMD) of the 20% yeast supplemented group was the highest (p < 0.01) (79.52%), and the 0% yeast supplemented group was the lowest (68.78%).

In this simulation, you will investigate how the concentration of an enzyme affects the total activity of the enzyme. In Nampukdee et al. Use pipette to add 2% sucrose to tube 3. 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. This means that Tube 4 contained the highest fermentation rate which allows the hypothesis to be accepted. Background:___________________________________________________________. .image-2x3 { In this simulation, you will learn about DNA profiling. margin-left: calc((100vw - 1170px) / 2); It occurs in the absence of oxygen. 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. If a terminal electron acceptor (such as Erlenmeyer flask Place the pH probe into the clamp on the metal stand. Then, if applicable, you will find the diopter required for a corrective lens prescription that improves the patients vision. } 29 Oct. 2013. . In this simulation, you will view animal and plant cells under a microscope, identify and label basic cell structures on micrograph images, and label cell structures on animal and plant cell diagrams. Use pipette to add yeast to each tube. dejar de crecer el flujo. respiration. Lower the pH probe until the pH probe is three-quarters inside the beaker of water. The rate of fermentation is estimated . Water, To determine the rate of fermentation, I will measure the hight of the CO2 bubble produced. Follow all standard laboratory safety procedures.

The inconsistent swirling caused the results of the pH to be inconsistent with the trend line and resulted in bad readings. This contains the small tube in a closed environment without oxygen. respirometer to remove the carbon dioxide generated. Since the sucrose will now produce twice as many pyruvate molecules which are later converted to ethanol, this means twice as much CO2 is produced, as a result lower pH levels.
