Effect of insulin on carbohydrate metabolism of the bivalve molluscMeretrix casta (chemnitz)
The effect of injection of insulin intoMeretrix casta has been investigated. Insulin lowers the blood glucose level significantly after an hour following the injection; recovery sets in later. Increase of dosage of insulin produces increased lowering of blood glucose.
Injection of insulin produces an increase of glycogen content in the digestive diverticula and foot but there is a differential effect of insulin on the glycogen content of digestive diverticula and foot. The former seems to be a labile storehouse of carbohydrates and the latter a more stable store, with probably some mechanism of regulation.
