The majority of known principal chain enzymes in the flight muscles of insects has previously been demonstrated. It is assumed, therefore, that the energizing metabolism of this highly specialized tissue proceeds in the customary manner. A number of peculiarities were discovered, however relatively low lactic dehydrogenase and relatively high glycerol-l-P-oxidase P esteric phosphate. Further attempts to classify and understand these deviations lead almost inescapably to the plotting of enzyme distribution patterns, i.e., the systematic coordination of the quantitative factors connected with enzymatic activities that are related functionally.
