Title: Enzymes

Aim: To investigate the effect of temperature on the rate of enzyme-controlled reaction.

Materials:

- Water bath

- Ice

- Thermometer

- Potato

- Ruler

- Measuring cylinder

- Stop watch

- Hydrogen peroxide

- Scalpel or blade

- Test tubes.

Method:

1. Pour 2ml of 3% H2O2 into a test tube.

2. Place a 1cm3 of potato in the test tube and place the test tube in a water bath of 50 oC.

3. After 20 minutes measure and record the height of the foam produced.

4. Repeat the procedure of varying temperatures of 40 oC, 30 oC, 20 oC, 10 oC, and 0 oC.

5. Based on the results obtained, plot a graph of 'rate of reaction' against 'temperature'.

Theory:

- Discuss the effects of temperature on enzyme controlled reactions i.e. in extreme cold, optimal, and extreme heat.
