Quick answer in an enzyme reaction, there is a hyperbolic relationship between the rate of reaction and the concentration of substrate, explains a university college london website resource. Objective: to analyze the effect of substrate concentration on the activity of enzymes theory: enzymes are protein molecules that act as biological catalysts by increasing the rate of reactions without changing the overall p.
Experiment to show enzyme reaction rates using yeast, hydrogen peroxide, and filter paper rates are measured by observing filter paper sink and then float as the peroxide is broken down into oxygen and water. In order to study the effect of increasing the enzyme concentration upon the reaction rate, the substrate must be present in an excess amount ie, the reaction must be independent of the substrate concentration.
