In two and three, we basically want to show that this Mikayla's methane equation actually correctly describes this blue curve here. So let's begin by going to the beginning of that chemical reaction. So at the beginning of the chemical reaction at a time of approximately zero, we know that the substrate concentration is very, very low. So the substrate concentration is somewhere around this value here at the beginning of that chemical reaction. Now let's compare the substrate concentration at the beginning to the Km value. Clearly the Km has a much higher value than the substrate concentration at the beginning.
