Description

1. The activity of glucose-6-phosphatase, glucose-6-phosphate dehydrogenase and malate dehydrogenase in the oyster eggs and the relationship between the egg nucleolus and egg periphery were studied.<br>2. It is the peripheral zone of eggs where some enzymes blocked in unfertilized eggs are released from the blockage and increases their activity remarkably after the fertilization.<br>3. Upon the insemination, the egg periphery evokes the activity of the creative area and the nucleolus.<br>4. Changing the direction of the first gradient axis parallel to the egg axis (the second gradient axis), KP axis regains its stability of position which has been lost by the insemination.<br>5. These changes of metabolism in oyster eggs are the primary event of fertilization.
