An Investigationinto The Effect Of Ph On The Activity Of Potato Tissue Catalase
An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase
Aim
The aim of my investigation is to see how pH affects the activity of potato tissue catalase, during the decomposition of hydrogen peroxide to produce water and oxygen.
Catalase + 2H2O2 Catalase + 2H2O +O2
Catalase + Hydrogen Peroxide Catalase + Water + Oxygen
Independent Variable
The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic. This is because the hydrogen and ionic bonds between –NH2 and –COOH groups of the polypeptides that make up the enzyme, fix the exact arrangement of the active site of an enzyme. It is crucial to be aware of how even small changes in the pH of an enzyme can affect activity until the enzyme will eventually become denatured.
The enzyme which is going to be used in this practical is catalase. Catalse is a very common enzyme which is found in almost all living and root......
