A substance that increases the rate of a chemical reaction without being consumed itself.
A biological catalyst that accelerates biochemical reactions within living organisms while remaining unchanged itself.
Homogeneous Catalysis: A type of catalysis where both reactants and catalyst exist in same phase (solid, liquid or gas).
