Yeast Fermentation Lab Report

Fermentation Lab Jocelyn Birt 9/29/17 Fermentation Lab Abstract: This lab’s purpose was to see how different levels of yeast, distilled water, and sugar interact to affect the level of carbon dioxide evolved in fermentation. In this experiment we had two sections. The first section tested four test tubes with varying levels of yeast, glucose and distilled water for evolved carbon dioxide levels. The tubes were timed for 20 minutes. The amounts of solution in the test tubes are noted in the methods

process of fermentation of yeast and the cellular respiration rate that is found in the mitochondria. The first part of the experiment tested fermentation of yeast through the production of CO2 under certain circumstances. Four different food sources were used: glucose, sucrose, starch, and H2O. The temperature varied from 37oC to 4oC and measured on a 5 minute interval. We predicted that the glucose on the highest temperature would produce the most CO2 bubbles. In the alcohol fermentation process

products and reactants. When using yeast, we monitor how it reacts with other items. It is used in the fermentation of beer and wine as well as the rising of bread. Yeast is a living organism and some food items depend on yeast to be successful. Hypothesis Certain items that contain garlic inhibits yeast and carbon dioxide. We are using different materials like cumin, cayenne, and cinnamon which has never been attempted so we are going to see if these items inhibit the yeast and carbon dioxide. Since these

Introduction Lab Three: Glycolysis, Respiration and Fermentation focused on the process of glycolysis and fermentation by measuring the rates of reactions when different carbohydrate substrates were introduced to the experiment. The metabolism of different types of carbohydrates differ because of the varying amount of bonds per substrate. Glucose has the smallest number of bonds, whereas starch has the highest. The number of bonds can either create a longer or shorter reaction due to the amount

Abstract Students conducted this experiment to study the fermentation that took place in yeast by observing the results of CO2 production in different test tubes. Glucose was readily available for the respiration of the yeast so CO2 was produced. In tube4 the evolution of CO2 was less than tube2 because of the grounded yeast. The presence of CO2 in tube5 was the least due to the addition of acetic acid in it because acetic acid in the fermentation led to a significant decrease in the concentration which

The student will use this lab exercise as the basis for writing a scientific method report. 2. The student will understand how the rates of chemical reactions are affected by temperature. 3. The student will understand the overall fermentation reaction by yeast, starting with glucose as an energy source. 4. The

Biology Lab Report Investigating Alcoholic Fermentation and the Affects of Yeast on Dough Aim: The aim was simply to investigate whether or not yeast had any affect on causing dough to rise when baked and to experiment with alcoholic fermentation eg. to see if it gave off carbon dioxide. Introduction: Following a few weeks of fermentation theory, groups of three to four were assigned and told to conduct a series of experiments involving the affects of fermentation. My group consisted of

Concentrations and Yeast Fermentation SOPHIE RICHARDS 11A MRS KIRK Abstract: This experiment was performed in order to determine the effect of the amount of sugar on Saccharomyces cerevisiae (yeast) fermentation. This was done by investigating and testing the effect of the amount of sugar upon the yeast fermentation process, and documenting the rate of gas production for a 25mL by-product. This was completed by mixing solutions, that included 100mL of water, 5g of yeast and a gradual increase
