But the catalyst itself is not consumed in the reaction. There are a variety of ways that a catalyst causes the rate to increase. In all cases, the catalyst speeds up a reaction by lowering the activation energy. An enzyme is a substance produced by a living organism that acts a catalyst in biochemical reactions.
