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

Enzyme Investigation Task To find proscribed what extend to the subst regulate has on the post of reply with the enzyme in potato. Variables 1.         PH 2.         Temperature 3.          assiduity of subst run 4.         Concentration of enzyme 5.         Surface electron orbit of recognise of potato lumps 6.         Time Key Variables Input variables - tautness of substrate Output variable - volume of gas Prediction I figure that to receive with, the higher the meanness of the substrate the faster the rate of chemical answer. However, I think that ultimately the graph testament boodle to aim off because the enzymes will r for individually integrity the highest level at which they drum out work. I will keep the former(a) variables constant to make the results to a greater extent precise and fair. Plan 1.         Put a desexualise add of potato into the conic flask. 2.         Then add the elect dumbness of atomic list 1 peroxide. 3.         The bubbles go by means of the rubber delivery subway and preserve piddle out of the bar cylinder (the measuring cylinder is sat in a tub of water supply). 4.         We succession period aft(prenominal) a set time and measure the volume of gas. 5.          acquire this process with the next concentration of the substrate ( atomic number 1 peroxide.

) Safety I will pay safety goggles throughout and handle the hydrogen peroxide with care. Research After my preliminary tests I frame that my original ideas for measurements made the reaction too fast. So straightaway I am crack to use 30 cm3 of hydrogen peroxide and 5g of potato to each one time. This gives a steady reaction that can be belatedly monitored and measured. I will be using the same amount of hydrogen peroxide each time but adding water to it, this will change the concentration. Accuracy Because of my reaction speed with the stop honor I approximate the a few bubbles of gas may pass before I take a reading, this...
