    In this experiment, water and potato enzymes were mixed to create a solution and placed into three test tubes. The first test tube was placed in 0 degrees Celsius, second test tube 22 degrees Celsius, and third in 95 degrees Celsius. The null hypothesis is when the temperature is changed; the concentration will not be affected. The alternate hypothesis is the more the temperature increases, the more the concentration decreases; as the temperature decreases, the concentration increases.…

    The abiotic factor being tested here is what effect the temperature of the yeast’s environment has on its ability or inability to reproduce efficiently. The lab tests the yeast in three separate temperature settings: a cold temperature (4ᵒC), room temperature (22ᵒC), and a hot temperature (30ᵒC). Here, the independent variable is the temperature of the yeast habitat and the dependent variable is the amount (in mL) of CO2 gas produced by the yeast.…

    The two types of fermentation that are well known are alcoholic fermentation as well as lactic acid fermentation. Fermentation is vital for many organisms, such as yeast and bacteria, because it allows them to obtain energy required to carry on life processes. Alcoholic fermentation is especially important for human beings, as it is used to produce alcoholic beverages, bread, and many other everyday items that are consumed (Alba-Lois, 2010). On the other hand, lactic acid is a waste product of certain bacteria (Lactobacillales), which is utilized to create many dairy products such as yogurt and cheese. In addition, humans can resort to lactic acid fermentation when oxygen is limited, so it is used as an extra source to obtain oxygen. In our experiment we will be using yeast, a single-celled organism that utilizes sugar as a food source, and it produces energy substances through the breakdown of sugar molecules. Specifically, the type of sugar as a source of food, impacts the speed of fermentation in yeast. In this lab, we will calculate the rate of fermentation in yeast with different solutions of sugar, such as sucrose, fructose, and lactose with glucose being the control. It is important to humans that the yeast uses the best sugar source during fermentation, as it creates important everyday items we consume like bread, alcohol, and…

    The Effect of Temperature on the Enzyme Catalase

    The aim of this experiment was to investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature), 0 degrees Celsius (freezing), 100 degrees Celsius (boiling), and 37 degrees Celsius. Along with variations in temperature, the experiment involved different amounts of the two solutions being used. Using a spot plate containing 12 wells the different mixtures of hydrogen peroxide and water were as follows: 40 drops of pure hydrogen peroxide (H2O2), 20 drops of tap water and 20 drops of hydrogen peroxide, and 10 drops of hydrogen peroxide and 30 drops of tap water. The results after all experiments combined can be summarized. The reaction between hydrogen peroxide and yeast catalase increases as the temperature increases. This experiment proved to be an effective way of meeting the aim because it left room for several readings along with room for simple changes.…

    Abstract – The problem that led to this experiment was that when antibiotics were mixed with yeast cells, the antibiotics decreased the yield of yeast cells. However, this is unexpected result because yeast is not a bacteria and therefore antibiotics should have no effect on them. The hypothesis that was tested was that antibiotics decrease the yield of yeast cells. In general the materials that were used in this experiment were a clean hemacytometer, a pipette, a solution of yeast with no antibiotics (culture A), and a solution of yeast…

    Alcoholic Fermentation Lab

    When we experimented we set out all of our materials. Our materials were a fermentation bottle, one rubber stopper, one bubbler, one measuring beaker, 2 ml of yeast, 10 ml of warm water, and 30 ml of corn syrup. The first step we took was taking the measuring beaker, measuring 10 ml of warm water, and adding the 10 ml of warm water to the fermentation bottle. We then took the measuring beaker again, measured 2 ml of yeast, and added the 2ml of yeast to the warm water in the fermentation bottle. After that, we mixed both yeast and water gently until it was thoroughly dissolved. Then we took our measuring beaker again, measured 30 ml of corn syrup, and added the corn syrup to the mixture in the fermentation bottle. Soon after that, we swirled our mixture together. Then we put the rubber stopper on the fermentation bottle. We then took our bubbler and filled the bubbler with water until the water settled into the bottom and up to fill the two lines. We then inserted the bubbler…

    The ideal temperature for yeast growth is between 30 and 35 degrees Celsius depending on the type and if there is a sufficient food source. The lab will test whether yeast would release more carbon dioxide provided that there was sugar at room temperature or in an incubator? The incubator will be set at 37 degrees Celsius and the room temperature is 22 degrees Celsius.…
