which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide. Procedure For our experiment we used‚ three test tubes‚ nine milliliters of potato

concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary‚ we were trying to find out how osmosis actually occurred in potatoes‚ and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction‚ which is stated below. The following apparatus was used for the preliminary: * 1 large potato (skin intact) * 3 boiling tubes * Set
