Description: A peroxidase enzyme‚ which was extracted from a brassica compestris (turnip)‚ is tested under various conditions in temperature‚ pH level‚ and competitive inhibitor (hydroxylamine). ABSTRACT: In order to determine the properties of an enzyme‚ a peroxidase enzyme was extracted from a brassica compestris (turnip) and tested under various temperatures‚ pH levels‚ and by a competitive inhibitor (hydroxylamine). The enzyme activity was measured in various ways depending on the activity

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

Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them

According to the results in this lab Jell-O must contain protein due to the fact that the meat tenderizer was able to break down the Jell-O much the same as it would break down the proteins in meat. 5. Did the amount of meat tenderizer give different results? The amount of meat tenderizer did give different results‚ cup â»2 with the least amount of tenderizer did not break down as much as the cup â»3 with the most tenderizer. Conclusion According to this lab it demonstrated that Jell-O does

Cavanaugh Lab: Tuesdays at 1pm Enzyme Kinetics Lab Introduction: Enzymes are proteins that will catalyze reactions to make the rate of the reaction occur faster than it would without. It can also make the reaction occur in the first place. Tyrosinase is an enzyme that has a variety of functions and activities. It produces pigments like melanin and others that would be apparent when a fruit is cut in half and it browns. (Bien-etre 3).There is that one function that stands out and the enzyme is continuously

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Osmosis and Scientific Method Lab Report Abstract The purpose of the lab is to see how different size potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

Biology Lab: Catalase (Enzymes) Abstract In this laboratory exercise‚ studies of enzyme catalase‚ which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The laboratory was also conducted in association with a second laboratory that measured the effects of an inhibitor on the enzymes. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration

Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific
