Document Summary
Study questions march 21: vo = kcat [s] / km + [s] = kcat [s] / km (if you have very low substrate concentration) *so if you"re looking at a michaelis-menten curve, you would be looking at the bottom left where there is a low substrate concentration. Km = binding and catalysis (kinetics and thermodynamics) If kcat/km is high, we have a great enzyme where the slow step is the diffusion of the substrate into the membrane. All ethyl esters with the only difference being the side chain on the amino acid (gly, val, tyr) The one that binds the best is tyr since it has the lowest km value. But this doesn"t tell us much about catalysis so we need to look at kcat. The kcat/km value gly is the worst for both km and kcat and thus the ratio is the lowest too and the worst.
