Digestive enzymes function as biological catalysts that accelerate hydrolysis reactions by destabilizing transition states, thereby reducing the activation energy required for macromolecular catabolism. This mechanism operates strictly within the domain of biochemistry and physiological metabolism, adhering to the fundamental principle that enzymatic efficiency is governed by substrate specificity and induced-fit conformational changes. The concept establishes the theoretical foundation for understanding how proteases, lipases, and amylases facilitate the thermodynamic feasibility of nutrient breakdown without altering the overall Gibbs free energy of the system.
