Enzymes are biological catalysts that accelerate chemical reactions in living organisms. They are typically proteins, although some RNA molecules can also function as enzymes. Enzymes are crucial for various biological processes, including metabolism, digestion, and DNA replication. Each enzyme is highly specific, meaning it catalyzes only one particular reaction or a small group of related reactions. This specificity is due to the unique three-dimensional structure of the enzyme, which allows it to bind to specific substrates and catalyze their conversion into products.

Enzymes work by lowering the activation energy required for a reaction to occur, thereby increasing the rate of the reaction. They do this by temporarily binding to the reactants, forming an enzyme-substrate complex. This complex lowers the energy barrier for the reaction to proceed, allowing the products to be released more quickly than they would be without the enzyme.

Enzymes are regulated by various factors, including temperature, pH, and the presence of specific inhibitors. Some enzymes are activated by the presence of certain molecules, while others are inhibited by the binding of specific compounds. Enzymes play a vital role in maintaining homeostasis within cells and are essential for the proper functioning of all living organisms.
