What affect the substrate has on the rate of reaction with the enzyme in potato?

…

…the temperature of the room in which the experiment is being done. I would also try and find a way to keep the size of my potato lumps more consistent so the variation in surface area does not affect my results. If I was going to do this experiment again I would also use some higher concentrations than where I stopped in this experiment because I could see the predicted curve of the line better.
