Detailed explanation-1: -As the substrate concentration increases, the enzyme reaction increases until all of the active sites are occupied by the substrate. When all active sites are occupied, the enzyme is saturated. At this saturation point, adding more substrate makes no difference to the reaction rate.
Detailed explanation-2: -The conditions under which a particular enzyme is most active are called the optimum conditions. When an enzyme is most active the rate of the biological reaction it catalyses is highest.
Detailed explanation-3: -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. At low temperatures, an increase in temperature increases the rate of an enzyme-catalyzed reaction.
Detailed explanation-4: -Maximal Velocity (Vmax): Increasing the substrate concentration indefinitely does not increase the rate of an enzyme-catalyzed reaction beyond a certain point. This point is reached when there are enough substrate molecules to completely fill (saturate) the enzyme’s active sites.
