WebFeb 12, 2024 · This enzyme-substrate complex is called the enzyme intermediate. The intermediate then reacts with water, which displaces the remaining part of the initial substrate and reforms the initial enzyme. Chymotrypsin, like most enzymes, is specific in the types of substrates with which it reacts. WebThe simplest model of enzyme-substrate interaction is the lock-and-key model, in which the substrate fits precisely into the active site (Figure 2.24). In many cases, however, the … WebWhen an enzyme binds its substrate it forms an enzyme-substrate complex. Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction. cinema-600-sound-bar
