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. But before we actually begin our derivation, we want to simplify this equation. So instead of using the equation that describes equilibrium, we're going to assume that we're essentially at the beginning of that equation. So right at the start when the time is approximately equal to zero, and at this point in time the velocity of that enzyme is equal to v naught.
