Catalyst

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process. It lowers the energy needed for the reaction to occur, allowing it to happen more easily or quickly. Catalysts are important in many areas, including industrial processes and biological systems. For example, enzymes are biological catalysts that help facilitate reactions in our bodies, such as digestion. By increasing the efficiency of reactions, catalysts play a crucial role in many scientific and practical applications, making processes faster and often more energy-efficient.
