Term Papers 4 pages, words To investigate the effect of temperature on the enzyme Catalase. To investigate the effect of temperature on the enzyme Catalase.

Average final volumes of oxygen for each concentration of hydrogen peroxide. Evaluation Overall, I believe my experiment went well and that I gained sufficient results because I repeated each concentration three times and investigated eight concentrations in total.

We will conclude the experiment by establishing the enzymes optimum temperature the temperature at which it works best at. We will also carry out some simple experiments using the substrate Hydrogen Peroxide.

Delivery tube Using the equipment safely It is important that we use the apparatus carefully, as safety will be an issue through out the whole experiment.

We will wear goggles and an apron, to protect our eyes and clothes. As we are using enzymes and Hydrogen Peroxide we need to be extra careful, ensuring they dont come in contact with our eyes and skin. We also must be careful when using hot water, being careful not to burn ourselves. Therefore through out the whole experiment we shall be very careful in our actions around the lab.

C the experiment should not proceed as the energy needed for enzyme action is unavailable Control Experiment The control experiment for this investigation will be the experimental setup Catalase is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and oxygen.

We will measure the amount of Oxygen released from the Hydrogen Peroxide.

In order to do this we will use an inverted measuring cylinder. This piece of apparatus measures the amount of Oxygen given off, measuring in ml. This will help us measure the amount of Oxygen more accurately. To make the test fair the following parameters must remain constant during the experiment.

These parameters are water, Hydrogen Peroxide, Catalase, room temperature and the duration of the reactions. If the reaction reacts too quickly we may dilute the solution.

By insuring this test is fair, we will gain accurate results.

Introduction

Volume of Hydrogen Peroxide, volume of Catalase solution, concentration of Hydrogen Peroxide, concentration of Catalase. This is because a rise in temperature increases the rate of most chemical reactions and a fall in temperature will slow them down.

This is particle theory. I am going to investigate the temperature at which reactions occur. I predict an increase in temperature will result in an increase in kinetic energy.

Since the speed of particles increases, they should collide more often and therefore the speed of reaction increases. The particles will also have more energy thereby speeding up the reaction even more.

It has been suggested that for every 10 degree rise in temperature, the speed of the reaction will double.Investigation - Hydrogen Peroxide An investigation into how the concentration of the substrate 'hydrogen peroxide' affects the rate at which it is broken down to oxygen and water by the enzyme catalase.

Class practical or demonstration Hydrogen peroxide (H2O2) is a by-product of respiration and is made in all living cells. Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell.

Hydrogen peroxide is merely produce of course in chemical reactions, but the cells have to acquire rid of it before it builds up in a big sum. A cell uses contact action to interrupt down the H peroxide into H2O and O.

Hydrogen peroxide will traveling to feed into the contact action and it is traveling to interrupt that down into two merchandises. Hydrogen peroxide (H 2 O 2) is a by-product of respiration and is made in all living cells.

Hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell. Cells make the enzyme catalase to remove hydrogen peroxide. Investigation - Hydrogen Peroxide An investigation into how the concentration of the substrate 'hydrogen peroxide' affects the rate at which it is broken down to oxygen and water by the enzyme catalase.

Hydrogen peroxide is released due to many metabolic reactions in the body, which gives toxicity to the living cells. Hence, there is a chemical need to remove hydrogen peroxide in a very rapid rate.
