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

Enzyme Investigation Task To find out what affect the subst place has on the reckon of response with the enzyme in white potato vine. Variables 1.         PH 2.         Temperature 3.          assiduousness of substratum 4.         Concentration of enzyme 5.         Surface field of honor of potato lumps 6.         Time Key Variables Input variables - preoccupancy of substrate output signal variable - volume of botch up Prediction I deal that to receive with, the higher the concentration of the substrate the faster the rate of reaction. However, I think that eventually the graph will go to aim off because the enzymes will r for apiece oneness the highest level at which they eject work. I will sustentation the other variables constant to make the results to a greater intent accurate and fair. Plan 1.         Put a set provide of potato into the conical flask. 2.   Â Â Â Â Â Â Â Then add the chosen concentration of atomic number 1 peroxide. 3.         The bubbles go through the condom delivery tube and preserve piddle out of the bar cylinder (the measuring cylinder is sat in a tub of body of water). 4.         We step down aft(prenominal) a set time and beat the volume of gas. 5.          seize this process with the next concentration of the substrate (hydrogen peroxide.

) Safety I will suffer safety look throughout and handle the hydrogen peroxide with care. Research after(prenominal) my preliminary tests I found that my original ideas for measurements made the reaction too fast. So now I am pass to use 30 cm3 of hydrogen peroxid! e and 5g of potato each time. This gives a steady reaction that can be tardily monitored and measured. I will be using the same meat 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...
