Abstract To know the energy budget of adult Tegillarca granosa, the sort, the activity, and the tissue distribution of some isozymes related with energy metabolism were tested in Tegillarca granosa by using the poly acrylamide gel electrophoresis technology. The result was that: quite like other biosome, Tegillarca granosa, a kind of lower mollusk, possessed aerobic respiration, anaerobic respiration, and hexose monophosphate pathway, three kinds of energy metabolism methods, and each way takes a significant role in the metabolic activity of adult Tegillarca granosa. However, aerobic respiration is obviously the most important of the three, while the other two are less important and only play auxiliary roles in its energy metabolism. As to the way of the energy absorption and expenditure, the degradation of esters and carbohydrates may be the main method of the energy intake, while the main channel of energy exhaustion are activities such as food digestion and muscle movement.
