Final answer:
Enzymes are organic catalysts that can change matter. They have an active site specific for their substrate and typically increase the rates of chemical reactions.
Step-by-step explanation:
Enzymes are organic catalysts that can change matter. They have an active site specific for their substrate, meaning that they have a specific location where their target molecule binds. Enzymes typically increase the rates of chemical reactions, rather than decrease them.
