Enzymes are biological catalysts, which are substances that increase the rate of a chemical reaction without themselves undergoing any permanent chemical change. In living organisms, enzymes are proteins that facilitate biochemical reactions essential for life. These reactions include digestion, energy production, muscle contraction, and nerve function. Each enzyme is specific for a particular substrate, meaning it will only bind to and act upon one or a small number of molecules. This specificity is due to the unique three-dimensional structure of the enzyme, particularly its active site, which is a region where the substrate binds and the reaction occurs.

Enzyme activity can be influenced by various factors, including temperature and pH. Most enzymes have an optimal temperature and pH range at which they function most efficiently. Deviations from these optimal conditions can lead to a decrease in enzyme activity or even denaturation, where the enzyme loses its functional shape and becomes inactive.

Enzyme deficiencies or malfunctions can lead to various metabolic disorders. These are often genetic conditions where a specific enzyme is absent or does not function correctly, leading to the buildup of toxic substances or a lack of essential products. Examples of such disorders include phenylketonuria (PKU) and Tay-Sachs disease. Understanding enzyme function and dysfunction is crucial in medicine, as it underpins the diagnosis and treatment of many diseases. Furthermore, enzymes are widely used in industrial applications, such as in detergents, food processing, and biotechnology.
