Front

Define the term 'substrate' in the context of enzymes.

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the significance of the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.
