Introduction:

Our practical was about examining the reaction of an enzyme in a particular type of food, in which the enzyme break down food and digest the existing proteins inside the materials (food). And to investigate the rate of the enzyme's reaction when its get influenced by different types of pH levels. The enzyme we chose for our lab is the Trypsin. The reason why we chose this particular enzyme is first, for the fact that Trypsin has a very high activity which means its reaction is fast and it digests proteins completely in short period of time. Second, it could still react with a wide range of different pH levels.

Our experiment was based on the theory that implies: reactions of the enzyme with very high or very low pH level will be very slow. While the reaction reach its high speed if the pH level is at 8 which is called as the optimum of the rate of reaction of the Trypsin.

Apparatus

The material that is used to perform the experiment is Milk solution.
