- 6.3: Kinetics with Enzymes
- An enzyme alters the pathways for the conversion of a reactant to a product by binding to the reactant and facilitating the intramolecular conversion of bound substrate to bound product, before it releases the product. Hence the following chemical reaction can be written to show in simplest terms how an enzyme catalyzes a reaction.
