Enzymes are biological catalysts. Enzymes are the catalysts involved in biological chemical reactions.

A catalyst remains chemically unchanged itself at the end of a reaction.

Each enzyme has a temperature that it works optimally in, which in humans is around 98.6 degrees Fahrenheit, 37 degrees Celsius –the normal body temperature for humans.
