An enzyme is a protein produced by a living organism that functions as a catalyst. Enzymes increase the speed and likelihood of chemical reactions within an organism's body by lowering the activation energy necessary for a reaction to occur. They are essential to all cellular functions, and life as we know it could not exist without them.
