Enzymes
Enzymes'Enzymes are biological catalysts. A catalyst is defined as a substance that increases the ra ... tance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow ... Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Enzymes have two main functions: To act as highly specific catalysts, and also to provide a way of c ...
