Investigating the Effects
Enzymes In Potato Have on
Hydrogen Peroxide Solution
My aim is to investigate the effects, enzymes in potato have on Hydrogen Peroxide.
In my investigation I could of used liver, but I will use potato instead. I have chosen to use potato because with potato I can time it. With liver I cant time it as it reacts with hydrogen peroxide quickly.
What are enzymes and how do they work?
Enzymes are biological catalyst, which speeds up the rate of reaction. Enzymes break up food so they can pass through easily. Enzymes, which break down starch, cannot break down protein or fat. There are three types of enzymes they are:
> Lipase: converts fats (big molecule) into fatty acids (small molecule).
> Protease: converts protein (big molecule) into amino acid (small molecule).
> Carbohydrase: converts starch (big molecule) into glucose (small molecule).
Enzymes work in three stages, these stages are:
1. Firstly the substrate (food) molecule moves into the enzyme lock.
2. Secondly the substrate fits enzyme forming an enzyme-substrate complex.
