Studies on the metabolic differentiation of claw, leg and heart muscles of the fresh water field crab (Paratelphusa hydrodromus/Herbst/) 1.
The heart muscle is characterized by a high glycogen, lactic acid, lipid and fatty acids content and by high activities of phosphorylase , LDH, SDH, and GDH as an adaptation to its dynamic action of constantly pumping blood. The leg muscles behave as "fast muscles" and are characterized by having high myofibrillar. ATPase activity and relatively high activities of LDH, SDH and GDH as compared to the claw muscle which may explain their repetitive action during walking. The claw muscle is adapted to a tonic function as revealed by its low myofibrillar ATPase activity, high glycogen, high lipid and low values of LDH, SDH and GDH which further support its tonic action of short duration.
