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. This happens because the enzyme selects the particular configuration of the substrate and bends the bonds into the energetically-favorable orientation, with a consequent decrease in entropy. They are essential to all cellular functions, and most life could not exist without them, although viruses lack enzymes, but use them from their host cell.<ref>http://www.medterms.com/script/main/art.asp?articlekey=3266</ref>
