The biochemist normally follow the method of either removing the substrate or add competetive inhibitor with the enzyme in order to understand the enzyme kinetic mechanism. This is possible because addition of an inhibitor helps in understanding the kinetic behaviour of the enzyme based upon the reaction co-ordinates. The change in experimental values of Vmax and Km thus help in identifying the nature of enzyme kinetics. For example, a competetive inhibitor, the Vmax remains same but Km changes. On the other hand, a non-competetive inhibitor causes change in Vmax but not Km.
Thus, depending upon these enzyme co-ordinates, the mode of action of an enzyme might be investigated.

BACKGROUND The first part of this assignment focuses on the thermodynamics of enzyme-catalysed reactions. To answer the questions posed you will need apply the following two equations. Note that you may need to re- arrange these equations to determine the value you need. You also need to take care with the units of the values you use and determine. The first equation defines the relationship between the change in free energy (AG ") and the equilibrium between the products and...
