Background Info on pH in Catal
A catalyst is a substance that speed the rate of reaction without being used up. Enzymes are the catalysts in biological processes. They are large proteins that speed up chemical reactions. The enzyme forms the active site from small numbers of amino acids.The active site is the location on the enzyme where the substrate collides and the reaction takes place. If the shape of the enzyme and the substrate do not match exactly then they do not bind. This makes sure that the enzyme does not work with the wrong substrate. Enzymes are not affected by the reaction, so when the products have been released, the enzyme is ready to bind with a new substrate.In my experiment the substrate was the hydrogen peroxide, the enzyme that we used was catalase and the product that was formed was oxygen and water.This can be explained by an equation:Enzyme + Substrate ProductCatalase + H202 H20 + 02This equation explains how the catalase in our experiment binded with the H202 to break it down and form oxygen.The induced fit theory says that the binding of a substrate to an enzyme causes a ch
As a result, this means the enzyme to catalyze a reaction has changed. Gases can flow easily and change their shape and their volume depending on the container. There are no forces to hold all the particles together. Enzymes also react at low temperatures, but when the temperature rises above 40 C their reaction rate start to decrease. Enzymes such as catalase work by lowering the activation energy. For others it is necessary to supply energy in order to start the reaction. Only a fraction of the total collisions cause a chemical change. Increasing the concentration of the reactants and raising the temperature make more collisions and therefore more fruitful collisions which increases the rate of reaction. Liquids can flow and change shape but they always have a fixed volume. They have more energy and move around faster. The fruitful collisions have sufficient energy (activation energy) to break the existing bonds and to form new bonds, which then form the products of the reaction. Which means the reaction must be successfulThe rate of reaction depends on how many successful collisions there are in a given unit of time. The activation energy is the energy required to start a chemical reaction. Gas - In a gas the particles are further apart.
