Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

Catalase Lab Introduction: Catalase is an enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism:

Title : THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Aim : To study the effect of pH on the activity of catalase. Introduction : Catalase‚ an enzyme found in many different tissues‚ catalyses the breakdown of hydrogen peroxide into water and oxygen. 2 H202 → 2H20 + O2 Hydrogen peroxide is a toxic substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide

Discuss two errors in attributions Attribution bias is the illogical reasoning behind people’s decisions about one’s own and others’ behaviour by giving objective views on situations‚ it is essentially faults in a process of elucidation and can lead to errors in interpretation of our own and other’s behaviour because: a) People are ‘cognitive misers’ – we do not examine all the evidence provided or we take mental shortcuts (linking to social cognition) to reach a conclusion‚ leading to wrong

and oxygen produced by the potatoes catalase reacting with hydrogen peroxide) was a kind of indicator of how the reaction was going. It almost indirectly related to the temperature increase‚ because every time the temperature was rising there also seemed to be foam also rising at the top of the hydrogen peroxide. As you can compare when the temperature started rising in my tests‚ my observations would also have a correlation to the foam produced by the catalase.

Trial and error is an experimental method of problem solving‚ repair‚ tuning‚ or obtaining knowledge. "Learning doesn’t happen from failure itself but rather from analyzing the failure‚ making a change‚ and then trying again." This approach can be seen as one of the two basic approaches to problem solving and is contrasted with an approach using insight and theory. However‚ there are intermediate methods which for example‚ use theory to guide the method‚ an approach known as guided empiricism.

Reaction of catalase with hydrogen peroxide AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast‚ potato or liver‚ speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogy…

Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This
