Catalysts are important in chemical reactions because they change the rate of a chemical reaction. However, catalysts themselves are not actually a reactant of a reaction. For example, magnesium oxide is a catalyst to hydrogen peroxide, which speeds up the rate that hydrogen peroxide decomposes.
Enzymes act as catalysts in biochemical reactions.
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.
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.

Enzymes act as catalysts in biochemical reactions.
They speed a chemical reaction. Add: Catalysts lower the activation energy needed to start a chemical reaction.

A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
element
Enzymes are proteins that act as biological catalysts. Catalysts are substances that accelerate a chemical reaction. They decrease the activation energy of a chemical reaction.
catalysts
Catalysts actually lower the activation energy needed to start a chemical reaction. This makes the reaction happen more easily.
