The fate of D-glucose-6-phosphate and phosphoenolpyruvate in homogenates of tail and claw muscles of the lobster (H vulgaris) has been studied. With both substrates oxygen utilization is higher for the claw than for the tail muscle. Succinate is not an end product of anaerobic D-glucose-6-phosphate-U- 14C degradation in either muscle but L-lactate is the major product of such catabolism in tail muscle whereas both L-lactate and L-alanine are produced in claw muscle. Dihydroxyacetone phosphate production was observed both tissues: this can be related to the known high lipid content of these tissues.
