Enzyme Investigation. Aim: To look at how enzyme concentration affects the rate of the reaction. I am going to be investigating how by changing the concentration of enzyme the reaction speed alters. This is part of our work on the function of enzymes, how they work and the effects of conditions on how they work. We have learnt about the formation of enzyme-substrate complexes, the lock and key model, induced fit model, activation energies of normal reactions and enzyme-catalysed reactions, equilibrium, specificity and denaturation. Firstly I would like to talk about the enzyme, catalase and the substrate, hydrogen peroxide. In organisms, hydrogen peroxide is a toxic by-product of metabolism of certain cell oxidations to be more specific. Hydrogen peroxide on its own is relatively stable and each molecule can stay in this state for a few years. Its decomposition therefore needs to be speeded up greatly in order to prevent it from...
