Enzymes are protein catalysts that dramatically speed up biological reactions by lowering activation energy. They exhibit high specificity, binding substrates at active sites and forming enzyme-substrate complexes. Models like “lock-and-key” or “induced fit” describe enzyme action. Factors such as pH, temperature, and inhibitors affect enzyme activity. Enzyme kinetics and regulation are foundational in biochemistry, medicine, and biotechnology.
