Final answer:
The induced-fit model describes the interaction between substrate and enzyme, highlighting the conformational changes that optimize enzymatic reactions.
Step-by-step explanation:
The interaction between the substrate and the enzyme is called the induced-fit model. This concept represents a more dynamic notion than the previous lock-and-key model, elucidating how the binding of a substrate catalyzes a slight configurational adjustment in the enzyme.
This alteration yields an optimal binding state that escalates the enzyme's ability to catalyze its chemical reaction.
According to the induced-fit paradigm, this change occurs as the enzyme and substrate merge, which not only reinforces the correct bonding but also stimulates the enzyme to contort the substrate into its transition state, augmenting the reaction rate.
A key summary point is that enzymes showcase varying levels of substrate specificity, and the induced-fit model explains how enzymes can accommodate substrates through conformational flexibility, enhancing biological reactions.
