Activity In Hepatopancreas Research Articles

Effect of eyestalk removal on phosphatases activities in hepatopancreas of the crayfish, Orconectes limosus (RAF.)

1. 1. The effect of eyestalk removal upon acid and alkaline phosphatase activities in hepatopan-creas homogenates and subcellular fractions of the crayfish ( Orconectes limosus) was studied. 2. 2. In intact animals activity of acid phosphatase was higher than that of alkaline phosphatase. 3. 3. The removal of eyestalks causes decrease in activity of both phosphatases.

Enzymatic activity in hepatopancreas of Nassarius obsoletus

1.1. Comparatively high levels of glucose-6-phosphate dehydrogenase were found in the hepatopancreas of Nassarius obsoletus. The absence of demonstrable levels of the second oxidative shunt enzyme suggests that only a partial shunt operates in the hepatopancreas for the generation of NADPH necessary for the synthesis of lipids.2.2. Both the high lipid content as well as the high relative mass of this organ is consistent with its possible role as both a major supplier of reduced metabolites and a significant site of lipid synthesis.3.3. In accordance with observations in other groups of snails (Coles, 1969b) no significant activity of lactic dehydrogenase was apparent in the hepatopancreas. High activities of malic dehydrogenase may function instead to reoxidize NADH arising in glycolysis. This may also be linked to the possible regulatory role of phosphoenolpyruvate carboxykinase in glycolysis.
