produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim: The aim is to investigate and determine the effect of change in pH on the activity of the enzymes catalase. Equipment: Test tubes Test tube rack Pipettes Stopwatch Ruler Pen Safety goggles Gloves Materials: Liver pureed 3% of hydrogen peroxide (H2O2) with few drops of detergent Safety: Hydrogen peroxide

used was the spark (the match). The Chemical reaction being tested was how fast the hydrogen peroxide could turn into water and oxygen. The theory that was being tested was; Enzymes speed up reactions. The facts that I wanted to determine were matches making the chemical reaction happen quicker or not.

Part one 1. a) When hydrogen peroxide was added to manganese‚ tiny bubbles formed in the solution- intensity of (1). b)The solution did not change in temperature. c) The bubbles stopped forming after about 18 minutes. 2. After we added 2 more mL of hydrogen peroxide‚ the reaction occurred again. Again‚ small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes. 3. After adding more manganese dioxide‚ the reaction occurred again. This

break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase was able to break down the hydrogen peroxide. The less absorbent the solution the harder it was for peroxidase to break down hydrogen peroxide

Catalase is a common enzyme found in the bodies of all living organisms in contact with oxygen. It is involved in reacting with hydrogen peroxide to convert it into water and oxygen and can do so with millions of hydrogen peroxide particles each second. These types of enzymes have many uses in bodily systems commonly known as proteins that speed up the rate of the metabolic process by regulating the chemical process which helps digest food and break down toxic substances. The most favourable conditions

organisms. The rate of enzyme activity is influenced by temperature‚ pH‚ and the presence of inhibitors. Catalase is an enzyme which is produced by every cell to break down hydrogen peroxide. Hydrogen peroxide is a waste product of cellular activity that is poisonous to cells. Catalase speeds up the decomposition of hydrogen peroxide into harmless water and oxygen gas. The purpose of this lab was to determine whether an inhibitor affects the rate of activity for the enzyme catalase. Since catalase

partners and I tested how time effects a catalase reaction. The amount of hydrogen peroxide was recorded after the reaction for the certain time given has taken place. We used sulfuric acid to stop the reaction with the catalase from occurring. This process is known as denaturing (Campbell 152). The potassium permanganate in this experiment was used as hydrogen peroxide indicator. It determined the amount of hydrogen peroxide remaining after the reaction occurred. Based on our experiment we observed

is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins that have a 3-Dimesional shape and contain a region called the

to maintain the internal environment [2]. Hydrogen peroxide is an oxidizing agent that can be decomposed by catalase [11]‚ the liver is able to decompose hydrogen peroxide enzymatically because it contains catalase [12]. The reaction rate of an enzyme catalysed reaction under the effect of changes in temperature was tested in this experiment. It was hypothesised that the fastest reaction rate would occur a 37 degrees Celsius. Liver and hydrogen peroxide were placed into 4 different test tubes‚ all
