5.6 Enzyme catalysis Enzymes are biologically developed catalysts. Enzymes are proteins, ranging in molecular weight from about 6000 to several million. About 150 kinds have been isolated in crystalline form. The diameter of enzyme usually ranges between 10 ~ 100 nm. Therefore, the enzyme catalysis borders the homogeneous catalysis and the heterogeneous catalysis. 10.5 Catalytic reactions Structure of nitrogenase （1）Enzymes
