Here's why:
* Active Site: This is the specific region on an enzyme where the substrate binds and the chemical reaction takes place.
* Substrate: This is the molecule that the enzyme acts upon.
* Product: This is the new molecule formed as a result of the enzymatic reaction.
The enzyme facilitates the conversion of the substrate into the product. Once the reaction is complete, the product is released from the active site, allowing the enzyme to bind to another substrate and catalyze the reaction again.
