are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide into oxygen and water. Since hydrogen peroxide is continuously produced by numerous metabolic reactions‚ catalase helps to prevent the body tissues from being damaged by the peroxide. pH is used to measure the acidity or basicity of a solution and is very important when chemical reactions are concerned.

Research question: What does the changes in the amount of substrate on an enzyme’s reaction effect on? Hypothesis: I forecast that the more concentrated the hydrogen peroxide is the higher the volume of the foam is and the less concentrated the hydrogen peroxide is the lower the volume of the

Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder thermometer

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

An enzyme that catalyzes the reduction of hydrogen peroxide is specifically known as catalase. This chemical reaction that is most catalyzed by catalase H2O2 decomposition to form water (H2O) and oxygen (O2). This chemical reaction is represented by the formula: 2 H2O2 → 2 H2O + O2 (gas) Hypothesis: If the chemical reaction‚ H2O2 decomposition‚ is catalyzed by an enzyme‚ then the rate of the chemical reaction will increase.

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

Most people choose hydrogen peroxide over rubbing alcohol to clean a wound since hydrogen peroxide doesn’t burn. However‚ when hydrogen peroxide is treated on deeper wounds into the flesh‚ it can pose numerous problems to cellular health. When hydrogen peroxide is used correctly to clean wounds‚ it becomes an oxidizer and can be used as a disinfectant to prevent infections. However when used incorrectly‚ hydrogen peroxide can cause oxidative stress on cells. This essentially means that there is an
