Energy metabolism during anaerobiosis and recovery in the posterior adductor muscle of the bivalve Scapharca inaequivalvis (Bruguiere)

1. 1. In the posterior adductor muscle of Scapharca inaequivalvis both aspartate and glycogen were substrates for anaerobic metabolism. ATP and arginine phosphate only contributed to a small extent. Alanine and succinate were major end products, whereas opines were minor end products. Lactate produc...

More Information
Summary:1. 1. In the posterior adductor muscle of Scapharca inaequivalvis both aspartate and glycogen were substrates for anaerobic metabolism. ATP and arginine phosphate only contributed to a small extent. Alanine and succinate were major end products, whereas opines were minor end products. Lactate production was not observed. 2. 2. The ATP turnover rate was reduced by a factor of 6 in the later anoxic period. Glycolysis and aspartate contributed about 90% either during the initial step or during the prolonged anoxia. 3. 3. Recovery of 24 hr was not enough for a complete restoration of energy reserves, whereas anaerobic end products were eliminated over this period. There was no strombine or lactate accumulation.
