A catalyst is a substance that speeds up the rate of a chemical reaction.
catalyst-by lowering activation energy
A substance that speeds up the rate of a chemical reaction without being consumed in the process is called a catalyst. Catalysts provide an alternative pathway with lower activation energy for the reaction to occur, increasing the reaction rate without being altered themselves.
catalyst
An enzyme is a substance that speeds up biological processes by lowering the activation energy needed for reactions to occur.
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
