Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine

compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are formed when water molecules (H2O) bond with

Task 3: Interpreting Debug Output. Note: If you already configured IP addressing on R1‚ please remove all the interface commands now before proceeding. Furthermore‚ R2 and R3 should be configured through the end of “Task 2: Basic Router Configuration”. Step 1 – On R1 from privileged EXEC mode‚ enter the debug ip routing command. R1# debug ip routing. IP routing debugging is on. The debug ip routing command will show when routes are added‚ modified and deleted from the routing table. For example
