And so this is data point number two, and now we add even more S concentration. And let's say we add this quantity and that corresponds to this data point here. And so we continue adding these data points. And eventually, every single time we do this for any enzyme, this is the curve that we're going to obtain. So notice what the blue curve tells us. Initially, at the beginning, when we have relatively little amount of S in that mixture, this blue curve will resemble a straight line.
