Lecture III: Quantitative Comparison of Models. A classic mathematical model for enzyme kinetics is the Michaelis-Menten equation: V= V max [S] K m +[S] Given data of V versus [S] for a particular enzyme and substrate, we can determine the Michaelis-Menten parameters V. max and K m using a regression procedure. Consider, for example, the ...
