Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. is this a linear relationship? what happens to the initial reaction rate as substrate concentration increases?

The relationship between substrate concentration and the rate of reaction of a reaction involving an enzyme as catalyst is not linear. At the start, the initial rate is high since there is high enzyme activity but as the reaction proceeds the rate of reaction gradually decreases as the substrate has all been used up.
