Enzyme-controlled reaction, factors that affect the chemical structure and properties of the enzyme.

Write an explanation of how any two factors affect the rate of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme, the pH of the solution, the concentration of the enzyme, substrate and the product. Also, another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all, I have …

…the key, being the substrate, fits only into that lock. The enzyme is totally specific and only catalases a single reaction. iii)In the prosthetic group are non-protein molecules. They are covalently (strongly) bonded to the enzyme and must be there for the enzyme to function properly. If removed they will most probably cause the enzyme to denature. They are one type of an enzyme co-factor. Such examples of this are haemoglobin, chlorophyll and cytochromes.
