Part II: Exploring the M-M equation

At this point, I'm going to show you the Michaelis mentioned equation. I'm not going to show you how to derive the equation, because the shortest derivation that I've seen is still over a page long. However, I will lead you through some intuitive approaches to this equation.

Funny looking equation, don't you think? Actually, I prefer to write the equation like this:

If you turn on javascript, this becomes a rollover

 

So, why did I say this is a funny looking equation? Well, for one thing, the independent variable [S] appears twice on the right-hand side of the equation. In a well behaved equation, we would really like to have the independent variable appear only once. Even worse, if you try to simplify the equation, it turns out that there is no simple way of writing the equation so that [S] appears only once. Darn!
