An enzyme is a protein or RNA produced by living cells, which is highly specific and highly catalytic to its substrates. Enzymes are a very important type of macromolecular biological catalysts. Due to the action of enzymes, chemical reactions in organisms can also be carried out efficiently and specifically under mild conditions. https://www.creative-enzymes.com/resource/Enzyme-Definition-And-Classification_18.html
