Once the substrate is tucked into the active site, the enzyme undergoes a slight change in shape (often called "Induced Fit") to grip the substrate tightly. This puts stress on the substrate's chemical bonds, making it easier for them to break or form.
The relationship between these three components is often explained using two primary models.
The substrate is the specific molecule upon which an enzyme acts. It is the "raw material" that enters the reaction.
To understand how they work, you have to look at the relationship between three key components: the , the substrate , and the active site . 1. The Enzyme: The Biological Catalyst
