Background Information Chemical reactions make or break of bonds between atoms. The total number of atoms remain the same, but the atoms appear in new combinations. There are three major patterns of chemical reaction which include synthesis reaction, decomposition reaction and exchange reaction. Basically, synthesis reaction is when two or more molecules or atoms come together to form a complex molecule. Decomposition reaction is when a molecule is broken down into smaller molecules or atoms. Exchange reaction is when molecules switch with other molecules so that different molecules are made. The substance involved in a chemical reaction are called…show more content…
Enzymes are very large and complex organic molecules. The rate at which an enzyme is called enzyme kinetics.The rate at which an enzyme works depends on many factors including the concentration of hydrogen peroxide, temperature, pH, and salt concentration. Enzyme catalyzed reactions also tend to go faster with increasing temperature until a temperature optimum is reached. Temperatures above 40-50 degrees Celsius denature many enzymes. The rate of the reaction should increase with increasing concentrations of substrate or hydrogen peroxide. A catalyst increases the rate of a chemical reaction without actually becoming part of the product or being changed itself. Enzymes can do this by binding to the substrates in the position for chemical interaction. The substrates are bound to the enzymes active site they undergo structural changes that make a new product. Since enzymes do not change they are reusable. Enzymes can catalyze millions of reactions each minute. Enzymes also determine which reactions are possible at a particular time. If there is no enzyme there is no reaction. Without enzymes reactions would go to slow to live. Many enzymes are produced in an inactive form and must be activated before they can actually start to work. Denaturation is a process where proteins or nucleic acids lose their structure by some external stress like a strong acid or base, or heat. When proteins in a living cell are denatured it disrupts the cell activity. Most substrates lose their function when denatured. Enzymes lose their activity because the substrates cannot bind to the active
