EFFECT OF DIFFERENT CONCENRATIONS OF AMYLASE WITH STARCH Hypothesis I predict that as the concentration of enzyme increases, the rate of reaction will increase. I believe this because most chemical reaction happens faster when the concentration is higher. At higher concentrations, molecules mover around faster therefore there will be more collisions; and this makes it easier for them to react together. Method 1. Using a pipette place the different concentrations of amylase (0.1,0.2,0.3,0.4,0.5) into the test tubes 2. Add 0.01 ml of starch to each test tube using a different pipette 3. Stand for 5 mins 4. Place each test tube into the colorimeter 5. Take the reading for each cuvette 6. Repeat if necessary to obtain accurate results Apparatus * Amylase (enzyme) conc. 0.1, 0.2, 0.3, 0.4, 0.5 * Starch * 5 test tubes * test tube rack * cuvettes * pipette * colorimeter ANALYSIS OF RESULTS The table of results is a record of the percentage light transmission for each particular...
