ANSWER: When the amount of enzyme is increased the reaction rate is increased. The liver contains the enzyme catalase that eliminates the hydrogen peroxide to break it down the oxygen and water. 2. Is there a “control” (control group or control sample) in this experiment? What is it? Review the concept of a “control” in experimental design if necessary. ANSWER: Yes there is a controlled group and it is in test tube A. 3. What information does this control provide? ANSWER: When there is no enzyme present, there is no reaction, 4. Why do we add water to some of the test tubes in this experiment? ANSWER: Water helps with enzyme solidity and helps promote high performance for a reaction rate. PART A – QUESTIONS: 5.

3. (a) What effect does an extreme high temperature have on enzyme function? (b) What is the cause of this effect, in other words what exactly happens to the enzyme molecules due to extreme high temperature? Explain your answer in detail and supported by research. ANSWER: In the higher temperature the enzymes in the liver were being broken down from the meat being cooked and making the enzymes nonreactive. 4. What happens to the liver homogenate when you cool it back down to room temperature and add more hydrogen peroxide? ANSWER: Once the enzymes were nonreactive and broken down, they did not respond to the hydrogen peroxide. PART B – QUESTIONS: 5. Create a bar graph describing your observations of the effect of temperature on catalase activity. All parts of a graph should be properly labeled or identified, including a short descriptive title for it Label the “x” and “y” axes with a brief description and identifying their measurement units properly. Your graph must be completely clear for anyone. You may lose points if anything in your graph is incomplete or unclear. Insert your graph in the space

Turnip Peroxidase Lab Report

The objective of this lab was to determine the best pH level to increase enzyme activity. As this objective was met, it was discovered that water (pH level 7) was the best for percent absorbance. The hypothesis for this experiment was, “If peroxidase is an enzyme and therefore contains certain pH tolerances, then when placed in solution with pH levels of three, seven, and ten and the reaction is measured by a colorimeter, then water will be the optimal solution for maximum reaction rate.” As seen in the tables and graphs, the data supported the hypothesis due to the fact that most enzymes have an optimal pH of 4-9.

The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

7. Will the temperature effect the pH Scale? Hypothesis: The hypothesis of this experiment is that the rate of reaction will increases well as the hydrogen peroxide concentration. If the temperature, pH and enzyme concentration is kept constant then the rate of reaction will start to decrease as well as the hydrogen peroxide concentration. Aim: To investigate the effects of changing the concentration of the enzyme catalase that it has on the rate of breaking down the Hydrogen Peroxide solution.

molecules produced per unit time). In order to do so, enzymes bind temporarily to one or more reactants, lowering the amount of activation energy needed and thus speed up the reaction. Most of the cells use an enzyme called catalase to reduce the amount of hydrogen peroxide, a toxic substance that could accumulate as a result of normal cell activity. The purpose of this experiment was to observe the effects that enzyme concentration and copper (II) sulphate would have on the rate of reaction. This experiment was divided into two parts: Part A and Part B.

After record your data and determine the absolute rate of the enzyme-catalyzed reaction. Based on the data and observations the hypothesis was accepted. It was accepted because when pH were changed to a variety of levels the transmittance began to get higher reaction rates. The increased absorbance means greater amount of product and a higher reaction rate will be produced.

The instructor began our experiment by creating a catecholase enzyme solution using a chilled potato. He did this by removing the skin of the potato, this was necessary because the catecholase is contained under the skin. Another, reason is because if the skin is left on then the reading of the spectrophotometer would be inaccurate since the skin is brown as well as the benzoquinone. The potato was kept chilled so that the enzymes were not denatured. Next, the instructor chopped the potato and placed the pieces in a chilled blender along with 500 milliliters of chilled, distilled water.

H20 + 2 O2 This experiment will use 1% catalase solution and 3% hydrogen peroxide solution, both diluted into water so the reaction slows down. Temperature will be controlled in this experiment to change the reaction speed of the enzyme and the substrate, this is what the experiment is looking at. The effect of the temperature will be determined by how much gas is released in two minutes, which will change the pressure inside the test tube and will be measured by a gas

Enzymes are proteins that acts as catalysts, increasing the rate of chemical reactions. With containing many different enzymes, enzymes prove to be viable molecules, as they can ultimately determine the many possible chemical reactions that take place within the cell.1With an enzyme able bind to the substrate through specificity, the substrate correctly orients itself binding to the active site. Once positioned, the enzyme can lower the activation energy of the reaction causing the chemical reaction to occur at a rapid pace. The efficiency of an enzyme can vary depending on the environment. Some factors may include temperature, pH, and differences in enzyme substrate concentration.

They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.

This happens because enzymes lower the activation energy, as they provide an alternative reaction pathway. The decrease in the energy level aids in making the process happen faster (Jae In Lee, 2011) A catalase is an enzyme, which is found in all living organisms. This enzyme helps to convert hydrogen peroxide into oxygen and water. Chemical actions that happen within the cell produces hydrogen peroxide, which is poisonous and therefore can kill the organism.
