This older theory suggests the substrate fits the active site perfectly, like a key into a lock. It emphasizes the rigid specificity of enzymes.
In short: the is the passenger, and the active site is the seat in the car. The seat facilitates the journey, but only the passenger is changed by the destination. Without the perfect fit between these two, the essential chemical reactions that keep us alive would happen too slowly to sustain life. difference between substrate and active site
In the world of biochemistry, enzymes are the unsung heroes that make life possible. To understand how they work, you have to look at the relationship between two fundamental components: the and the active site . This older theory suggests the substrate fits the
