The results you collected are presented below Part 1 Enzyme Dry Weight Absorbance at 580 nm 0.270 The Required dilution factor: 35 Part 2 p-nitrophenol absorbance at 400 nm: 0.731 You now need to analyze the results and calculate the following: (Answer each question to 3 significant figures) Part 1 Calculate the Dry Weight (DW) of your enzyme using the following equation DWenzyme = 0.35 . A580 . DF = 9 If the molar absorptivity of the p-nitrophenol is 7.28 mMcm and the path length is 1.0 cm, what is the concentration of p-nitrophenol in the sample? mM Using the formula below, what is the activity of your enzyme? Activity = 0.00728 * DWenzyme A400 * 1000 (Hmol/min.g) 60
