So we now have the substrate inside the active side and the enzyme will begin to transform that substrate into the product and once we form the product, it will dissociate from the active side to basically form these final molecules, the product and the enzyme in its individual form. Now going this way the rate constant is k two and going in reverse, the rate constant is k minus two. So this is the equation that basically describes what is taking place inside the beaker once we reach equilibrium, once we establish equilibrium. Now what we essentially want to do in this lecture is we want to derive the mathematical equation, the mathematical expression that basically describes this blue curve. So can we derive such an equation? And the answer is yes.
