Catalase investigation

Trial assessment Enzymes Aim The aim of this experiment is to see the effect of four different concentrations of amylase solution on the breakdown of starch. Prediction According to S-cool.co.uk ( Microsoft corporation 2000), "...Enzymes are proteins and have a specific shape. They are therefore specific in the reactions that they catalyse. One enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on the surface of the …

…experiment more than once - this would have ensured greater reliability and precision of my results as some of the outcomes may have been by luck ·Use a light brown colour instead of the mid brown colour - there were lots of problems when we were trying to judge the mid brown colour of the solution. This could of also affected the results as the rate of reaction was calculated by the mid brown value.
