Macromolecules are large molecules composed of smaller, repeating units called monomers. They are essential to life and include proteins, nucleic acids, carbohydrates, and lipids. Enzymes are a specific type of protein macromolecule that catalyze biochemical reactions in living organisms. They are crucial for various biological processes, such as digestion, metabolism, and DNA replication.

Enzymes achieve their catalytic function through a process called induced fit. When a substrate (the molecule an enzyme acts upon) binds to an enzyme, the enzyme's shape changes to create a more favorable environment for the reaction to occur. This interaction is highly specific, with each enzyme typically catalyzing only one type of reaction. The active site of an enzyme, a specific region that binds the substrate, is responsible for this specificity.

Enzymes can be influenced by various factors, including temperature, pH, and the presence of inhibitors. Optimal conditions for enzyme activity are usually within a narrow range, and deviations from these conditions can lead to denaturation, where the enzyme's structure is altered and its activity is lost.

Enzymes play a vital role in maintaining homeostasis in living organisms. They help regulate metabolic pathways, control the rate of reactions, and ensure that biological processes occur efficiently. Understanding enzymes and their functions is fundamental to fields such as biochemistry, medicine, and biotechnology.
