WebNov 16, 2024 · Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off. The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme. WebEnzyme-catalyzed reactions have saturation kinetics The velocity of enzyme-catalyzed reactions increases with the concentration of substrate. However, at high substrate concentrations, the quantity of enzyme molecules becomes limiting as every enzyme molecule is working as fast as it can.

How does substrate concentration affect enzyme activity?

WebEffect of Enzyme Concentration. The concentration of the enzyme is important in chemical reaction as it is needed to react with the substrate. Often a small amount of enzyme can consume a large amount of substrate. However, with the increase of enzyme concentration, the effectiveness of the active sites also increases, so these active sites ...
