Investigating how temperature effects the rate of enzyme reaction

I have been asked to investigate something which effects the rate of an enzyme reaction. Temperature, concentration of enzyme, ph, concentration of substrate, light, quantity of enzyme and quality of substrate all effect the rate of enzymes. I chose to write about how temperature effects enzymes because we've done about it at school.

Apparatus list

Timer (stopwatch)

Measuring cylinder

Water bath

Thermometer

Rubber tube

Sidearm flask

Gas syringe

Bung

Peroxide-enzyme

Balance

Step by step method

Firstly, you have to check the weight of the Peroxide enzyme on the balance, we need 5g Peroxide. You then put 5g Peroxide enzyme in a sidearm flask. The sidearm flask should be attached to the gas syringe. In the measuring jug you put in 10ml Hydrogen Peroxide, we use 10ml because it would be inappropriate to use more because the particles would be too much. Then put 10ml Hydrogen Peroxide in a measuring cylinder. Quickly put the sidearm flask into the water bath (the water should be a certain temperature depending on the temperature you want to do)
