I'm asked to calculate V

_{max}and K

_{M}from this, with and without the inhibior, and answer what kind of inhibitor it is.

I have plotted 1/

_{0}here:

The x-intercept is -1/K

_{M}. The value I get is -1/K

_{M}=-4E4, so that K

_{M}=25E-6. Does this mean that K

_{M}=25E-6 M? My book says 20-24 M. Of course, I might have been unaccurate in drawing the graph, but why do I miss by a factor of 1E6?
