a catalyst
A catalyst is a substance that speeds up the rate of a chemical reaction.
A substance that speeds up a chemical reaction without being consumed is called a catalyst. Catalysts lower the activation energy needed for a reaction to occur, allowing it to proceed faster, but they remain unchanged at the end of the reaction.
A substance that speeds up a chemical reaction is known as a CATALYST.
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".

A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
