To investigate the effect of temperature on an enzyme controlled reaction
Introduction and planning
For the investigation of enzymes, I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch.
The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions, we can record the rate of reaction by taking a sample out and test it with iodine solution to see if there is any remaining starch present.
We have to use the enzyme amylase because enzymes will only work on a specific substrate i.e. amylase will work on starch because of its special shape of active site. This is known as the ‘enzymes specificity’.
The enzyme amylase is used for hydrolysing starch and glycogen to form glucose and maltose. This enzyme is found in human saliva for the use of breaking down starch in food, enabling......
