    Enzyme - Simple English Wikipedia, the free encyclopedia

    Enzyme. The substances at the start of the reaction are called substrates. The substances at the end of the reaction are the products. Enzymes work on the substrates, and turn them into products. The first enzyme was found in 1833, by Anselme Payen .

    Chem4Kids: Biochemistry: Enzymes

    The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very, very specific and don't just grab on to any molecule. The active site is a specially shaped area of the enzyme that fits around the substrate. The active site is like the grasping claw of the .

    What Do Enzymes Do? | Reference

    Full Answer. The enzyme has a region called the active site, and this is what the substrate binds to. The enzyme and the substrate do not react with one another; rather, the enzyme brings down the amount of energy needed for the reaction to occur, the activation energy. Negative feedback will cease the reaction.
