Using the graph paper provided, plot the velocity of the reaction (v) against the concentration of BAPNA substrate ([S]). Fit a curve to the data and estimate the Vmax and Km. How would you describe the relationship between the amount of product formed and the substrate concentration? For example, would you say that it is a linear, hyperbolic or exponential relationship?

a) The Michaelis-Menten plot
Using the graph paper provided, plot the velocity of the reaction (v) against the concentration
of BAPNA substrate ([S]). Fit a curve to the data and estimate the Vmax and Km.
How would you describe the relationship between the amount of product formed and the
substrate concentration? For example, would you say that it is a linear, hyperbolic or
exponential relationship?
