The extract that you are using was produced by crushing potatoes tubers in water, then filtering and centrifuging the extract produced to remove the cell debris. Hydrogen peroxide is easily broken down by the enzyme peroxidase as follows: - 2H2O2 2H2O + O2 Enzymes are important ...continue... Some properties of enzymes: 1. They are always Proteins 2. They are specific in their actions. (This means that each enzyme controls one particular reaction, or type of reaction.) 3. They can be used over and over gain.

(The...
