Enzymes are resourceful catalysts for biochemical reactions, like all catalysts enzymes tend to speed up reactions. Enzymes use alternative reaction pathway of lower activation energy. They take part in the reaction, and as a result their able to provide alternate pathways. Throughout the reaction enzymes remain unchanged because they cannot experience any permanent changes Enzymes consist of active sites, which are parts of the enzyme molecule that have the ideal shape and functional groups to bind to one of the reacting molecules. The reacting molecule that binds to the enzyme is called the substrate. An enzyme-catalyzed reaction takes a different direction than a reaction without catalyst. When the substrate binds to the enzyme a reaction
