All chemical reactions in living organisms need enzymes in order to work, build molecules and break down molecules require enzymes. Enzymes are biological catalysts. They act as catalyst to accelerate a chemical reaction. Catalysts enzymes work by weakening the bonds that lowers the activation energy. They help break down large molecules into smaller molecules, which helps speed up chemical reactions known as our digestive enzymes. A chemical reaction takes place at the active site between the enzyme and the substrate which releases a new substance also known as the product. The active site is a region of an enzyme molecule which binds to the substrate. The temporary bond allows a decrease in activation energy that is required to activate…show more content…
The more enzymes the quicker the reaction will be until the substrate is completely used up. Same with the substrate, if there are more substrates than the quicker the activity, until the enzyme is fully saturated. The pH is described as how acidic or basic a solution is. If the pH is lower than 7, it is considered an acid. Acids tend to donate hydrogen ions. If the solution is a base than the pH would be greater than 7, which means that the substance accepts hydrogen ions. Basically has the pH of a solution increases, the more hydrogen ions the enzymes will lose, which will cause it to lose its active shape. Temperature is another factor that affects enzyme activity. As the temperature increases, the enzyme activity will also gradually increase. Enzymes have an optimum range at which they will work the fastest. Different enzymes have different optimum ranges at which they perform the fastest. If the enzyme exceeds the optimum range than it will cause the enzyme to denature or in other words, unfold or lose its shape. Temperature can either increase or decrease the activity of the

Background: Enzymes are defined as proteins which allow some chemical reactions to take place much quicker than like reactions would occur. Enzymes are not changed by the reaction therefore they can be recycled over and over again. Enzymes function as a catalysts meaning that they speed up the rate of the metabolic process (Royal). The site where the product and substrate come together is called is the active site. Each enzyme accelerates a specific reaction and requires a specific enzyme; end products
