Publisher Summary Sea mussels exposed to air utilize carbohydrates as the main energy source and form several end products during valve closure (anaerobiosis). This chapter discusses a study for the identification of control sites in glycolysis in Mytilus edulis. The enzyme profile may indicate the rate limiting enzyme steps, which fuels are likely to be degraded and which end products may be expected. The adductor muscle shows low activities of hexokinase, glycogen phosphorylase, phosphofructokinase and glycerol-3-phosphate dehydrogenase but exhibits a clear activity of phosphoenolpyruvate carboxykinase. The gradual change in the control sites of the glycolytic flux is concomitant with the gradual shift in the route of glycogen breakdown. |
