Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the

Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed

Investigating the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed
Premium Enzyme Catalase Catalysis
Introduction In this experiment I shall investigate how the enzyme concentration can affect the initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down hydrogen peroxide into the products water and oxygen. To observe this catalase activity I used small amounts of liver samples slightly smaller than the size of a pea to see the reaction when hydrogen peroxide is added to it. In this experiment I exposed the liver samples in three different temperature environments: 3°c‚ 22°c‚ and 75°c. I wanted to measure

Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

wringing‚ pacing‚ nail biting‚ and heavy breathing are common signs of stress. People also feel physically different when they are stressed. Butterflies in the stomach‚ cold hands and feet‚ dry mouth‚ and increased heart rate are all physiological effects of stress that we associate with the emotion of anxiety. Stress is caused when a person is very angry or depressed and cannot control the anger or depression so he or she holds it in making him or herself stressed out. This can cause that person

The kid didn’t realize and know what the long term effects until he have experienced it. There are many chemicals found in cigarettes that can cause lung failure‚ heart problems‚ cancer‚ and even death.
