the effect of enzyme concentration on the substrate

The Effect of Concentration of Substrate Starch on the Rate of Reaction of the Enzyme Amylase
Brief
An enzyme is A compound that catalyzes biochemical reactions. Enzymes are proteins,which act with a given compound (the substrate)to produce a complex, which then forms the products of the reaction. The enzyme itself is unchanged in the reaction; its presence allows the reaction to take place. The names of most enzymes end in -ase, added to the substrate (e.g. lactase) or the reaction (e.g. hydrogenase).
Enzymes are extremely efficient catalysts for, and very specific to particular reactions. They may have a non-protein part (cofactor), which may be an inorganic ion or an organic constituent (coenzyme). The mechanism of action of most enzymes appears to be by active sites on the enzyme molecule. The substrate acting with the enzyme changes shape to fit the active site, and the reaction proceeds. Enzymes are very sensitive to their environment-e.g. temperature,pH, and the presence of ...
