Enzymes are protein molecules that act as biological catalysts, enhancing the rate of chemical reactions without being consumed in the process. The mechanism of enzyme-catalyzed reactions can be explained by the lock-and-key model, where the enzyme's active site fits a substrate molecule like a lock fits a key. Enzymes lower the activation energy required for a chemical reaction, thereby making the reaction proceed faster.

The enzyme-catalyzed reaction mechanism can be described in four steps: substrate binding, transition state formation, catalysis, and product release. First, the substrate binds to the enzyme's active site, forming an enzyme-substrate complex. This complex then undergoes a transition state, which requires an input of energy to break the chemical _________ ______ ______ ___ _________ ______ _____ ______ ___ ___ ___.
