For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch.

For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two substances have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme amylase can only break down starch to dextrin. I am going to do this by planning an experiment, carrying out the experiment, recording any relevant results and plotting graphs from which I will be able, to gain a strong conclusion. I will finally evaluate the whole investigation.

Before the experiments start we will be given a bottle containing a 1% suspension of starch and another bottle containing a 1% solution of the enzyme amylase. From these bottles I will be able to take out as much of either solution as I wish. I cannot start the experiment until I know which factors I am going to change and which I am going to
