Unfertilized eggs of the sea urchin, Pseudocentrotus depressus, showed a low level of oxygen consumption and did not accumulate lactic acid under anaerobic conditions. On addition of adrenalin the oxygen consumption was not accelerated and lactic acid was not accumulated, showing that the glycolytic process did not operate in unfertilized eggs. In hypotonic sea water, the unfertilized eggs swelled and produced lactic acid under anaerobic conditions and showed a relatively high level of oxygen consumption, unless they exhibited cytolysis. Under these conditions, the effect of adrenalin could not be observed. It is assumed that the intact structure of the cell and the interaction of the glycolytic process with some other metabolic processes may be required for adrenalin to affect the glycolytic process in unfertilized eggs. In contrast in nomal fertilized eggs lactic acid was accumulated under anaerobic conditions and the rate of production was accelerated by adrenalin. Oxygen consumption was also increased by adrenalin. In fertilized eggs, the rate of accumulation of lactate decreased in hypotonic sea water to the level of that of unfertilized eggs under the same conditions. Adrenalin had no effect on lactate production of fertilized eggs in hypotonic sea water.
