    • 5 Pages

    Increased production of CO2 is a result of increased temperatures acceleration of the rate of fermentation. Abstract: We have tested the affects of increased temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water‚ 2mL Yeast suspension and 6mL glucose of which 3 were at 25°C and 3 were at 37°C. The flasks at 37°C had each mixture pre-heated at 37°C for 2 minutes before being combined and then added to the flask where it was put into the bath

    The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

    Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of an enzyme is to increase the rate of a reaction;

    Alcoholic Fermentation Lab Kylie Johnson 11-10-12 Introduction: Since we are regular human beings‚ of course we are going to consume a lot of energy in our lifetime. Most of the energy we consume comes from fossil fuels. Fossil fuels are a nonrenewable resource‚ and we are using these non-reusable ones uncontrollably. This is why we need to use more renewable resources. A way that we could do that is by the alcoholic fermentation of ethanol. Ethanol is a byproduct in corn‚ and it is one product

    African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

    Introduction The purpose of this lab was to calculate and determine the optimal dosage of ultraviolet (UV) light to expose Saccharomyces cerevisiae (S. cerevisiae) to that would result in a survival rate of 20-40%. Saccharomyces cerevisiae commonly referred to as baker’s yeast is a single-celled eukaryote. Yeast is capable of growing as either a haploid or a diploid cell. The diploid cell can reproduce mitotically or sporulate‚ a process initiating meiosis and forming an ascus with four spores (Sacchromyces
