2. LO: Investigate the effect of temperature on the enzyme amylase
Define the following terms:
A catalyst - substance that speeds up a chemical reaction but is not used up or involved in the reaction and can be used many times over
An enzyme- large protein molecule that acts as biological catalyst
The active site of an enzyme- area in structure of enzyme with unique shape that binds to specific substrate
Give three clear examples of the type of reactions that are catalysed by enzymes
building large molecules from smaller ones
changing one molecule into another
breaking down large insoluble molecules into smaller soluble ones

LO: Investigate the effect of temperature on the enzyme amylase
Write up
Draw a diagram of the apparatus
write a method.
Identify variables.
Present and analyse the results: calculate rates of reaction using raw data and graphs. Students plot a line graph of enzyme activity at different temperatures.
Conclusion - using ideas about collision theory, active site, and denaturation in their answer.
