So at this moment in time, very little product P has actually formed. And so the reverse reaction of the formation of the product, this reaction here, becomes negligible, and we can basically remove that from our equation and this will simplify our equation and that will allow us to actually derive the equation that we're looking for. So this is the equation that we want to use. Now, what exactly is our starting point? Well, the starting point is right here. So we essentially begin by studying how that enzyme is functioning.
