In a biological system, the rate of reaction may occur very slowly, or in some cases not at all. This is due to the absence of an enzyme. Most enzymes tend to be large protein molecules, with a three a dimensional shape. Unlike chemical catalysts like manganese dioxide, enzymes are specific. The meaning to that is that, each enzyme will normally catalyse only one reaction. In order for the enzyme to catalyse it must join the substrate.
