Consider an enzymatic reaction in which the initial concentration of substrate is low. If the amount of enzyme is held constant, but the amount of substrate is increased, the rate of an enzyme catalyzed reaction will

Question

Quizplus · Accepted Answer

The rate of the reaction will initially increase linearly with increasing substrate concentration until the enzyme becomes saturated with substrate molecules. At this point, the reaction rate will plateau and remain constant even with further increases in substrate concentration. This is known as the maximum velocity (Vmax) and is reached when all enzyme molecules are saturated with substrate molecules.
