Now the point of making this simplification was to basically simplify this equation because what we actually want to do in step two is we actually want to describe the equation that describes how the curve behaves at the beginning of that particular reaction. So V Naught is equal to v max multiplied by this ratio. And because our denominator is Km plus the subsid concentration and as a result of this assumption we see that our denominator simply becomes Km. So this is approximately equal to v max multiplied by the substrate concentration divided by Km. Now instead of having the Km underneath this term, let's bring it underneath the V max term. And this is the equation that we have.
