The effect of concentration of enzyme and enzyme substrate on the rate of an Enzyme-catalysed reaction

This experiment go out be an investigation into enzyme activity. Wherever enzymes be used one has to bear in mind that in that respect be various factors which affect the enzyme activity. I will be look into how diametrical concentrations of the enzyme catalase affect the rate at which henry bleach is broken down into water and oxygen. In order of doing this different concentrations of liquid catalase that is gained from dried yeast will be added to a fixed volume and concentration of hydrogen peroxide for a fixed time length. Enzymes are protein molecules that theatrical role as catalysts, that is they stinker speed up a chemical reaction bit non being trans make in that reaction. They work by lowering the activation vitality of a chemical reaction. In order to bring to reactants together, energy has to be expended. Enzymes lower that energy barrier. When discussing enzyme catalyzed reactions, the participants in the reaction are called the substratums. Enzyme pra ctice their effect on chemical reactions by providing a fall out for the substratums to act and in some cases by introducing strain in the substrate molecules. Enzymes are proteins which have a complex trey dimensional social organization (tertiary complex body part).

someplace within the structure is a place where the substrate or substrates can act with the enzyme; this is called the active site and the structure formed by the interaction is called the enzyme-substrate complex. One important characteristic of enzymes is that they are specific. Because of the structure of the active site, only one substrate or a group of structurally related substrates can interact with a given enzy me. This means that there must be an enzyme ! for each reaction that the cell needs to perform. Conversely, if the cell does not contain an enzyme that can interact with a particular substrate, that substrate will not be converted...
