In our previous discussion we focus on the following graph and we said that the graph describes how the rate of the enzyme in an enzyme catalyze reaction changes when we change when we increase the substrate concentration. So as we increase the substrate concentration, as we make the Xvalue greater we see that the yvalue, the reaction velocity v naught, the rate at which the enzyme catalyzed the reaction basically increases and it follows the following blue curve. So initially at the beginning of that reaction, we have a relatively straight line, a straight slope, and then the slope begins to decrease and it levels off and eventually it begins to approach asymptotically the maximum velocity, the maximum rate of that enzymes activity, this red horizontal line. And notice the blue curve is never going to pass that v max value. Now, we also were able to actually derive the equation, the mathematical expression that describes the blue curve and this is known as the Michaelis Methan equation and this is the Michaelis Methane equation. So this equation describes this blue curve here.
