Substrate (Biology)

Key Stage 4

Meaning

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

The substrate is the chemical that an enzyme will affect.

About Substrates

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