Every living organism contains an unimaginable variety of the different biochemical structure known as substrates. There is the raw material and the building blocks required to build or repair our tissues or cells. Substrates are components necessary for one of another's of the life processes and they flit about ready to be used. In so doing they come near and enzyme and are attract to an active site - if they fit exactly into this precisely shaped site, and only then, something happens; for one tiny moment the substrate and enzyme form a precise unit. The biochemical reaction for which this enzyme has been constructed then takes place. When the substrates are in large in size, it is surrounded by a whole series of enzymes which alter it bit by bit. They are biochemical factories with enzymatic conveyor belt activity.
Most enzyme activities involve cleavage of a substrate. Only about 3 to 5 % of the enzymes combine substrate, synthesizing instead of cleavage. These are the anabolic enzymes and not the cleavage (catabolic) enzymes. When cleavage takes place, the substrate which fits into the active side is broken down and the pieces are the released in two portions. There are the two products of the reaction. One product may be regarded as waste and is used to produce re substrates after it has been broken down into its remaining biochemical components. The other product is a new substrate which can now search for a different enzyme to undergo another change. This process continues until a product is finally produced that has a particular function within the organism. The process resembles an assembly line for the step by step manufactured of parts and components which are then put together to finally build an automobile.
