Figure 3

A comparison of the time course of insulin effects on ⁴⁵Ca²⁺/Na⁺exchange and fluid phase uptake ([¹⁴C]insulin) by isolated denuded R. pipiens oocytes at 20–22°C, plotted as rate of change per unit time (dy/dt). The values are in pmols/oocyte for ⁴⁵Ca²⁺ and [¹⁴C]inulin, respectively. Each point presents a pooled sample of 5–10 sibling oocytes and the values shown are typical for 4 experiments in late winter-early spring. For details see Methods.
