This is the substrate concentration and the kinetic slopes from lab experiment. I'm suppose to construct a graph to estimate Km and Vmax (that's where I need help. How do I do that? Also, I'm suppose to construct another graph of "linear transfored" plot (lineweaver-burk or Eadie-hofstee plots) to determine Km and Vmax. HELP!
[So] | vo uninhibited | vo inhibited |
0.0833 | 0.2791 | 0.0924 |
0.1667 | 0.3822 | 0.1485 |
0.2500 | 0.3893 | 0.2182 |
0.4167 | 0.4320 | 0.3149 |
0.6667 | 0.5001 | 0.4480 |
0.9167 | 0.4813 | 0.5515 |
by enzyme kinetics equation is
ploting graph between 1/s0 vs 1/v0
intercept gives 1/Vmax and slope gives KM/Vmax
by ploting graphs in excel slope and intercept obtained are
1. uninhibited 1/Vmax = 1.9041 , Vmax =0.525
slope = Km/Vmax = 0.1384, Km = 0.07266
2. inhibited 1/ Vmax = 0.8289, Vmax =1.2064
slope = Km/ Vmax = 1.1643, Km = 1.4046
