WebEnzymes and Reaction Rates. Chemical reactions occur when molecules interact and chemical bonds between them are formed or broken. Some reactions will occur just by putting two substances in close proximity. For example, iron in the presence of oxygen will form iron oxide, or rust. Other reactions require energy to get the reaction started. WebEnzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
