Active Site

Key Stage 4

Meaning

This diagram shows an enzyme, substrate and the active site of the enzyme.

An active site is the part of an enzymes which is where the enzyme interacts with a substrate.

About the Active Site

The active site is shaped to fit with only one substrate so enzymes all have specific roles in an organism.

When an enzyme becomes denatured the substrate can no longer fit into the active site preventing the enzyme from functioning.
