海胆胚胎受精后1~4分钟，细胞内pH升高0.3个pH单位。PH的升高是启动发育所必需的。这种增加是由于细胞外的Na+交换细胞内的H+所致。
The intracellular pH of the sea urchin embryo increases 0.3 pH units between 1 and 4 min after fertilisation. The increase in pH is required for initiating development. The increase results from an exchange of extracellular Na+ for intracellular H+.
