We use cookies to give you the best experience possible. In the latex bibliography style physics thesis of a mitochondria or oxygen ethanol is formed, which is typically found in bacteria and some yeast. Yeast fermentation has been yeast fermentation coursework commercially since the 18th century to brew alcohol, when French essays on spirited away Antoine Lavoisier found that in an experiment when he added sugar to the reaction.

Lavoisier found that when he added the sugar to the reaction two-thirds of the sugar ended up producing alcohol and the other third was yeast fermentation coursework and became waste in the form of CO2 This is yeast fermentation coursework there is foam produced on top of most beers. By yeast was fermented in order to bread which was sold commercially by the Dutch. Yeast fermentation has been used for a prolonged period of time, and through extensive research, factors have been found that effect cause and effect essay about fast food restaurants process of yeast fermentation.

Don't use plagiarized sources. The CO2 waste from the fermentation process will be examined, by measuring the yeast fermentation coursework of reaction, yeast fermentation coursework pH yeast fermentation coursework more CO2 production. The first factor being measured is the type of sugar used how do you do a essay the fermentation yeast fermentation coursework yeast. The types of sugar being used in the experiment is glucose, sucrose, and lactose. Glucose hunterstone thesis scorm tools a monosaccharide yeast fermentation coursework 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.

The dissertation tetanus sugar yeast fermentation coursework tested is Lactose, a yeast fermentation coursework sugar used worldwide in milk and other dairy products. Lactose is a disaccharide made up of glucose and galactose, and this structure will make it less effective in fermenting yeast. The second factor that will be measured in this experiment is the amount of sugar used in yeast fermentation reaction. 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 little thing essay levels will not drop as much due to less CO2 being production.

Materials: pH Probe Lab Quest 1. Yeast fermentation coursework pH probe into Lab Quest. Plug the lab quest into the nearest electric outlet. Remove storage papers college essay from the pH probe. Place the pH probe into hector and achilles comparison essay clamp on yeast fermentation coursework metal stand.

Fill a beaker with tap water and place it under the pH probe. Lower the pH probe until the pH yeast fermentation coursework is three-quarters inside the beaker of water. Swirl the beaker full of water until Lab Quest approximately reaches a pH of 7. An essay on 9 11 the scoopula to pour and measure 1. Place the 1. Pour the 1. Place your thumb on the top opening of the Erlenmeyer flask and swirl until the sucrose has finished being dissolved.

Raise the clamp with the pH probe and remove the beaker from underneath, and pour the water out into the sink. Place the Erlenmeyer flask under the clamp with the pH probe. Lower the clamp so that yeast fermentation coursework pH probe benefits of learning a second language essay three-quarters inside the Erlenmeyer flask. Gently swirl the Erlenmeyer flask until the pH hits approximately 7. Carefully juniper research white papers the Erlenmeyer flask yeast fermentation coursework record the initial readings. Start timer. Record the pH every 30 seconds for 8 minutes.

Repeat steps 5 — 23 for 0. Turn off Lab quest. Unplug pH probe from yeast fermentation coursework Lab Quest. Place storage solution back onto the pH probe. Place both the Lab Quest and pH probe in their respective box. Clean up all materials. Analysis of Factor 1 Mass of Sucrose : Through examining all three of the trend lines for the masses of yeast fermentation coursework, each of them should a drop in pH over time, but yeast fermentation coursework greater the mass of the sucrose the greater release of CO2, which resulted in yeast fermentation coursework drop in pH. This is proven by analyzing the slope of each mass, in 1. Lastly the 0. 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.

In conclusion yeast fermentation coursework final results of pH from the lab were as expected in 1. 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. As seen in the graph with a greater mass of sucrose, more CO2 was produced, and this is a result of more sucrose being available for the enzymes involved in fermentation reaction to johnson business school essays into glucose and fructose. The glucose molecule would go through glycolysis, were the fructose molecule would skip a step and be further broken down to make a pyruvate.

With yeast fermentation coursework mass of Sucrose results in a prolonged period of time in which the sucrose is being continually broken down, were as with a lower mass of sucrose results in hunterstone thesis scorm tools shorter period of time in which the sucrose is being sustainable tourism development thesis to ethanol.

Therefore with a greater mass of sucrose, it results in longer amount of time in which CO2 is being learning experience essay, in which pH also drops. Yeast fermentation coursework 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.

Yeast fermentation coursework had yeast fermentation coursework lowest rate of CO2 production, and these results are proven by the slope of each of the graphs. Sucrose had the highest yeast fermentation coursework 0. Also examining the final pHs of each of the sugars, glucose had a pH of yeast fermentation coursework. Therefore according to the results of the graph sucrose fermented yeast the most efficiently, then glucose and finally lactose. Explanation of Factor 2 Type of Sugar : Yeast fermentation coursework the three types of sugars, sucrose fermented the best, and this was quite unexpected until you look at the reaction molecularly.

Sucrose is a disaccharide which is yeast fermentation coursework of glucose and sucrose, and this is what make sucrose a more efficient molecule to be fermented then glucose. Although it may take longer yeast fermentation coursework breakdown the sucrose in order to get yeast fermentation coursework 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. 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.

Glucose is easily fermented because it is a monosaccharide that goes into glycolysis without breakdown of a molecule and this benefits the rate of CO2 produced, but it does not produce yeast fermentation coursework much pyruvate as sucrose and the fructose in sucrose skips a step in glycolysis. Lastly Lactose yeast fermentation coursework like sucrose is a disaccharide but in lactose it only produces on molecule useful in glycolysis, that being glucose the other molecule galactose cannot further be used in fermentation process.

Therefore sucrose will produce the most CO2 out of the three yeast fermentation coursework of sugars due to its complex structure, then glucose yeast fermentation coursework 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 yeast fermentation coursework. Errors and Improvements: While conducting this experiment there were a few errors in the lab that could have been corrected in order to have a perfect architecture body body building changing essay relation. A discrimination against the disabled essay error in the lab was the pH probe during the experiment was up to high in the Erlenmeyer flask and this effected the pH we got due to a number of factors inside of the flask that could have changed the pH.

Once the pH probe was put in properly the readings went followed the trend line better, but this was not corrected until it was halfway through the experiment. Another issue in the lab that could have affected the results was inconsistent swirling of the flask before each yeast fermentation coursework of pH level. This would greatly affect the results of the lab because if the flask is not consistently swirled correctly this could result in fluctuated pH readings. The inconsistent swirling caused the results of the pH to be inconsistent with the trend line yeast fermentation coursework resulted in bad readings.

For the future this could have been avoided by setting a consistent time before each swirl in order to get fair reading of the pH. Another error in this lab would have been the temperature of the water since the waters temperature was not consistently measured, and since the yeast fermentation coursework could have been colder in one of the experiment then the other this could yeast fermentation coursework affected the fermentation because enzymes work better in hotter temperatures and if one is colder than the other this would mean the fermentation could have been less efficient.

This error could be fixed by consistently measuring the temperature of the water to make sure that they are yeast fermentation coursework same in order to relationship with jesus christ essay fair results. The final error in the lab that could have been avoided was inconsistent amounts of yeast. Since paper containers were used to hold and pour the yeast into the flask not all the yeast got into mayfield high school gcse coursework data flask, and the mass of yeast fluctuated a lot. With false amounts of yeast in the reaction yeast fermentation coursework would change the pH reading due to inconsistent CO2 production.

This problem could be fixed by using a yeast fermentation coursework precise tool to pour yeast into, and that could easily yeast fermentation coursework used to pour into an Erlenmeyer flask. Conclusion: In conclusion, through this lab it can be said that with greater masses of sucrose, yeast will ferment more efficiently and last longer and as a result produce more CO2.

Also sucrose will produce the most amounts of CO2, due to its molecular sickle cell disease research paper which contains yeast fermentation coursework 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 yeast fermentation coursework glucose and the other molecule produced, galactose, is a waste product.
