An Investigation into the effect of substrate concentration on the activity of the enzyme catalase.
Introduction
This experiment is designed to examine how the concentration of the substrate (Hydrogen Peroxide) affects the rate of reaction of the enzyme catalase.
Catalase is a particular protein. ... It would be possible to increase the speed of reactions by simply increasing the temperature, but for the temperature to have a significant effect on the rate of reaction the temperature would have to be raised to a level that would kill the organisms by disrupting their membranes, as well as being expensive energetically. ...
Activation Energy
In many reactions, the substrate will not be converted to a product unless it is temporarily given some extra energy. ... They achieve this by holding the substrate in such a way that their molecules can react more easily. ...
Active Site
A few of the amino acids on the surface of the molecule fold inwards to make a specific indentation, called the active site, into which a particular substrate can fit.
