The addition of Cu2+ (0.1-1.0 mM) to respiring, unfertilized eggs produced a marked stimulation in the rate of respiration whereas Zn2+ had no effect over the same concentration range. In the absence of Cu2+, temperature had little effect on unfertilized egg respiration but the Cu2+ stimulated respiratory rate showed the more normal response with a Q10 of 1.86 (10-20 degrees C). It appears that perch egg respiration is rate-limited by a physical event and it is suggested that Cu2+ may act by dissipating an oxygen permeability barrier located at the chorion.
向正在呼吸的未受精卵中添加0.1 - 1.0 mM的Cu2+会显著刺激呼吸速率，而在相同浓度范围内Zn2+则没有影响。在没有Cu2+的情况下，温度对未受精卵的呼吸影响很小，但Cu2+刺激后的呼吸速率表现出更正常的反应，在10 - 20摄氏度时Q10为1.86。看来鲈鱼卵的呼吸速率受一个物理事件限制，有人提出Cu2+可能通过消除位于卵膜的氧气渗透屏障起作用。
