Induced fit The matching between an enzyme's active site and the substrate isn’t just like two puzzle pieces fitting together (though scientists once thought it was, in an old model called the “lock-and-key” model). Its three-dimensional shape allows it to act only on specific molecules, referred to as the . The name of the enzyme is catalase.Enzymes work best within a certain pH range, and, as with temperature, extreme pH values (acidic or basic) can make enzymes denature.Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. In highly acidic or basic conditions, the structures of enzymes change. Suitable enzymes such as cellulase break down dead root matter and convert them into simple sugars, which thereby feeds beneficial microbes.This animation of how enzymes work is a basic rundown of enzyme functions and illustrates what enzymes do.Auteur : EFSAchannel The reaction is: 2H 2 O 2 → 2H 2 O + O 2.
