    Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

    Erin Arroyo  Lab report June 11‚ 2013 Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract:  In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature

    Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

    solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus the volume of sodium hydroxide added. III.Background Information: Volumetric analysis is the use of volume measurements to analyze an unknown; a method of this is titration. Titration is most often used to analyze the amount

    This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

    Lab Report 1708 Mrs. Himler Ryan Nelson 9/20/2024. Lab Report INTRODUCTION: During this lab‚ the group used 3 food thickeners. These thickeners are used to thicken‚ stabilize‚ and prevent separation for our daily products such as ranch‚ ice cream‚ and other dairy products. The group used modified food starch‚ corn starch‚ and guar gum. They all are different from each other‚ each in a unique way. Firstly‚ guar gum is like pectin‚ a soluble fiber and polysaccharide. Furthermore‚ the body cannot digest

    Purpose: The purpose of this lab was to observe and understand the effects of changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will

    Abstract A buffer is a solution that resists changes in pH when H+‚ OH-‚ or H20 is added. By using standard lab equipment‚ a lab pro diagnostic tool‚ and acidic and basic solutions‚ the pH can be found. By recording the pH while adding a base or an acid gradually to a buffer solution you can find the capacity of each buffer to resist drastic changes in pH. The best buffers will keep a solution from becoming either too acidic or basic with the addition of a strong base or acid. Introduction The
