Key Stage 4
Meaning
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.
