Answer:

Catalyst is a substance that influences the rate of reaction without being consumed in the reaction.

They increase the rate of reaction by decreasing the activation energy of the reaction.
As they are not used up in the reaction they are required in a small quantity.
In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
Few examples of catalyst are: potassium permagnet, platinum, enzyme (like hexokinase, hydrolase etc) etc.
