Enzyme Investigation
Task
To find out what affect the substrate has on the rate of reaction with the enzyme in potato.
Variables
1.PH
2.Temperature
3.Concentration of substrate
4.Concentration of enzyme
5.Surface area of potato lumps
6.Time
Key Variables
Input variables - concentration of substrate
Output variable - volume of gas
Prediction
I think that to start with, the higher the concentration of the substrate the faster the rate of reaction. However, I think that eventually the graph will start to level off because the enzymes will reach the highest level at which they can work.…
