Abstraktne
In muscle tissue of lamellibranch molluscs and crustaceans (cf. Table for the species studied), high levels of malate dehydrogenase and low ones of lactade dehydrogenase were detected. There is a direct relationship between the value of MDH/LDH ratio and the capacity of organisms to withstand temporary anaerobiosis. Animals with high ratio may adapt to hypoxia by transition from aerobic metabolism to anaerobic one.
