Summary
The conditions were studied for the glycerophosphate oxidation by homogenate from locust flight muscle, and the O2-consumption was measured. Maximal oxidation rates were found with 0.087m glycerophosphate, 8 × 10−6 m cytochromec, 7 × 10−6 m DPN and pH 7.5. The production of dihydroxyacetone phosphate is followed by further oxidation steps, as could be shown by estimation of the different fractions of acid-soluble phosphate. Comparative studies were made on different insects and vertebrates. The rate of succinate oxidation by insect muscle was found to be ten times higher than that of vertebrate muscle. The relation of glycerophosphate oxidation to succinate oxidation is quite different in insects and vertebrates, but no difference could be detected between the two types of muscle metabolism of insects: the carbohydrate and the fatutilizing type.
