Hanna 1 Tyler Hanna Ms. Corynne Dedeo MCB 2000 Honors Laboratory 2 October 2017 Lab Report 4: Kinetics Purpose To determine the effect of enzymatic competitive inhibition on Vmax and Km kinetic parameters over various substrate concentrations. Data Presentation Table 3: Actual substrate concentrations Table 2: Inhibited enzyme absorbances over 70 seconds at increasing substrate concentrations Table 1: Uninhibited enzyme absorbances over 70 seconds at increasing substrate concentrations
