Abstract
- The efflux rate coefficients of sodium, potassium and chloride from immature oocytes of the toad Bufo bufo have been measured and found to be respectively, 0.0069, 0.0023 and 0.0034 min(-1).2. Replacement of external chloride by sulphate resulted in a fall in chloride efflux of about 50%. This has been interpreted in terms of exchange diffusion.3. The membrane conductance has been measured and found to be 0.14 x 10(-3) mhos cm(-2) in good agreement with the value calculated from the flux data, 0.12 x 10(-3) mhos cm(-2), after taking account of the chloride exchange diffusion fraction.
摘要
已对蟾蜍中华大蟾蜍未成熟卵母细胞中钠、钾和氯的外流速率系数进行了测量，结果分别为0.0069、0.0023和0.0034分钟⁻¹。
用硫酸盐替代外部氯离子导致氯离子外流下降约50%。这已根据交换扩散进行了解释。
已测量了膜电导，结果为0.14×10⁻³ 姆欧厘米⁻²，与考虑氯离子交换扩散分数后根据通量数据计算得出的值0.12×10⁻³ 姆欧厘米⁻² 非常一致。
