In this experiment, I can clearly understand the reaction of enzyme in our body. The visking tube acting as the model gut is suitable to resemble the small intestine in our body. After that, I know how to handle the visking tube correctly. Lastly, I learn that a simple mistake can lead to big mistakes in our result.

By doing this experiment, I am able to see a clear view on
how enzyme react on our body. This is a new experiment to me since I never
doing this type of experiment. The visking tube act as our intestine and
boiling tube as a digestive system. I am also know the food stuff in our
experiment containing many starch after doing this experiment. Even this experiment quite confusing but it make me memorise better the
concept of reaction enzyme on the food. From the colour change we can know the
either the food containing starch or not. When the mixture turn to blue
solution, it indicate that the food contained starch and orange colour show
that it containing glucose.

From this experiment, I gain a
lot of new knowledge. For example, the action of enzyme on starchy food. In
this experiment we need to use Iodine solution and at the end of the experiment
I know thw function of iodine solution which is to ensure the presence of
starch. When the starch is present, the iodine solution will turn to blue. I
also know why the starch turn blue when they was reacted with iodine solution. Moreover,
after the experiment finish I can conclude that enzyme activities will active
at their optimum temperature, which are 37. Any temperature that approaching to
37 degree is the suitable temperature too for the enzyme reacts. From the
results of our experiment, the temperature of 28 shows the higher velocity of
rate of reaction for enzyme compared to temperature of 20. This is because 28
is more approaching to 37 rather than 20. Overall from this experiment, I know
that the food must be digested by its own specific enzyme before it can be
absorbed in the digestive system.
