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

Enzyme Lab Experiments Problem: How can we demonstrate how enzymes work? What happens if we alter the environment of an enzyme? Materials: G;lucose Test Strips Test Tubes Pipettes Raw Hamburg Lettuce Potato Raw Liver Chalk Beakers Dairy Lactose Tablet Water Sugar Solo Cups Hot Plate Knife Gloves Skim Milk Glow Sticks Peroxide Hypothesis: 1. If we change the environment via temperature the glow stick will Its intensity will change 2. If hydrogen peroxide is added to a certain food liver

firm but not set‚ and cup â»3 with the most tenderizer was not set. 3. What did you observe after 1 night in the refrigerator? After 1 night of the Jell-O being refrigerated cup â»1 with no tenderizer was set and very firm‚ cup â»2 with the least amount of tenderizer was set but not as firm as cup â»1‚ and cup â»3 with the most tenderizer was not set but had a watery jelly like texture. 4. Does Jell-O contain protein? According to the results in this lab Jell-O must contain protein due

Lab No. 2: The Microscope Light microscopy The bright field microscope is best known to students and is most likely to be found in a classroom. Visible light is focused through a specimen by a condenser lens‚ then is passed through two more lenses placed at both ends of a light-tight tube. The latter two lenses each magnify the image. Limitations to what can be seen in bright field microscopy are not so much related to magnification as they are to resolution‚ illumination‚ and contrast

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

Biology 42: Lab 22 Selection & Microevolution Name ____________ Introduction: Using the Hardy-Weinberg Equation/Looking at Microevolution What are the factors that lead to evolutionary change? Using mathematical equations‚ Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population

Week 1 Lab Name_________ Part I - Directions: For the function we are going to estimate the area under the curve using the trapezoidal rule where n = 5 by doing the following: 1. Divide the interval into 5 equal pieces. How long is each piece? This will represent the width of the rectangles we will use to estimate the area in gray above. What will the x-values be for the endpoint of each piece? Width of rectangle = 0.4 .2 .8 1.6 2.4 3.2 2 2. Evaluate f(x) for x1 to x6

Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase
