Yeast

Yeast are single-celled fungi. Yeast cells use an aerobic process called alcoholic fermentation to produce energy in the form of ATP. Not only does this process convert glucose into ATP, but it also produces ethanol and carbon dioxide. Along with a few other classmates, I performed the “alcoholic fermentation in yeast” lab to find the ideal conditions for carbon dioxide production in yeast. Organisms obtain the energy they need from food. Yeast cells use sugars, such as glucose, as a food…

the process of anaerobic respiration of yeasts in the absent of oxygen. The enzymes in the yeast assist the breaking down of the glucose and released alcohol and carbon dioxide. The producing of carbon dioxide means fermentation is taking place. It can be affected by such as temperature and pH level. Some organisms use fermentation to produce ATP without oxygen. According to the graph above, the class results trend supported the hypothesis, as the yeast concentration increases, the rate of…

of a yeast infection is the vaginal area being affected by it. The reason is high susceptibility of the vagina to contract a vaginal infection. This, however, does not mean that the yeast infection is limited to vagina only. It can happen at almost any part of the body. You need not be afraid of the yeast infection as it is not a deadly disease. It can easily be treated if given the right yeast infection treatment. First of all, lets shed some light on yeast infections. To start with, yeast…

number of bubbles that have risen in the warm sugar water yeast mixture, number of bubbles that have risen in the cold sugar water yeast mixture, and the number of bubbles that have risen in the distilled warm water yeast mixture. Fill the given plastic container with warm water halfway. Place a thermometer in the plastic container, and record temperature. Acquire scale, position wax paper over platform, and measure 0.5 grams of yeast with scoopula. Obtain plastic test tube with a punctured…

affect the rate of fermentation in yeast is temperature. Providing the ideal temperature for yeast to conduct fermentation effectively is a fundamental part of activities such as baking bread or brewing beer. Some species of yeast undergo fermentation even when oxygen is present. Among…

Fermentation occurs in the body when there is a lack of oxygen supplied to the muscle cells, but also occurs in yeast and bacterial cells. In the body the fermentation process becomes significant during oxygen deprivation episodes, thus becoming the key method of ATP production. Cells tend to avoid fermentation considering the fact that generally, with the exception of strict anaerobes, yeast and some bacteria there is a reduced amount of ATP production in contrast to oxidative phosphorylation…

that we eat on a daily basic requires a lot more skill and science than one would think. The way that bread raises is with a vital ingredient called yeast. But what is yeast and what things affect the outcome that it makes. That is what I have researched and have come to inform people about. To know how bread works one has to know what yeast is. Yeast is a single celled organism that is a fungus. Normally…

Cellular respiration occurs in all living organisms. ATP is a molecule that is made from food. Yeast uses cellular respiration as well. While the process of cellular respiration occurs in yeast, carbon dioxide is produced. Stephanie Lamot of Northeastern Illinois University conducted an experiment on how different types of sugar have an effect on yeast. Her conclusions were that the more yeast added to sugar, the faster the production of CO2 is. Hypothesis: The rate of CO2 production…

and how yeast reproduces through budding.” (Wile, Jay) Before the experiment continues yeast should be explained. “Yeasts are microscopic, single-celled organisms belonging to the fungi kingdom,” (Castro, By Joseph) these fungi reproduce by a process called budding. In addition, this fungus is capable of converting sugar into alcohol and carbon dioxide. This experiment is able to show students the capabilities of yeast and give them more insight about Gods marvelous creations. Moreover, yeast is…

Alcoholic Fermentation in Yeast By: Jettica Williams BIOL 1107 Lab October 10, 2016 Prepared for Mrs. Whitney Lab Course Introduction: During this experiment, we investigated the alcoholic fermentation in a single- celled fungus, which is yeast. Fermentation is activity of decomposition carbohydrates whereas deterioration incurring foods have protein. During the fermentation process usually do not generate reek and usually produced carbon dioxide gas, but marked by hydrogen sulfide gas…
