What concept describes how a substrate molds an enzyme around itself?

The induced fit model describes how an enzyme undergoes a conformational change upon binding to its substrate, allowing the enzyme to mold itself around the substrate. This concept highlights the dynamic nature of enzyme-substrate interactions. Unlike a rigid structure, the enzyme adapts its shape during the binding process, which enhances the interaction and catalytic efficiency. The induced fit model emphasizes the flexibility of enzymes, showing that they are not merely passive structures that fit substrates, but rather active participants that adjust their shape to optimize the fit and facilitate the chemical reaction. This adaptability is crucial for enzyme specificity and activity, illustrating the importance of molecular interactions in biological processes.
