How catalase activity is affected by change in pH.

Introduction
An investigation is to be undertaken to investigate how a change in pH can alter the activity of the enzyme catalase.

It is important to run away out some research on the field that I am going to investigate, namely enzymes such as catalase, as it is important to understand their role in the living organisms and how their functions argon carried out.

Enzymes
An enzyme can be thought of as a biologic catalyst. It is a specific molecule which provides an alternate path for a reception to take place, thus lowering the activation cleverness and so therefore increasing the rate of reaction. Enzymes be needed for biological reactions to take place at significant place in the temperatures that occur in a given organism.

A theory for the function of enzymes is the lock and key model. This suggests that a substratum is able to bind to a region on the enzyme that is called an nimble site which is specifically complimentary to the substrate. Once the substrate and enzyme are weakly bonded to come inher, it is known as an enzyme substrate complex. The specific reaction can now be catalysed and once it is completed the enzyme splits from the new made products. It summarised below:





1.Substrate collides with enzyme
2. Enzyme-Substrate complex make.








3.



Products are formed 4. Products break free from enzyme,
and enzyme proceeds to catalyse another reaction.



E = Enzyme S = Substrate P = Product

The shape of an enzyme will sole(prenominal) fit and form a complex with a substrate of specifically complimentary shape. This explains how an enzyme is described as specific. Specificity is important for numerous reasons, mainly as it would be unfavourable for an...If you want to get a full essay, order it on our website: Orderessay
