Fig. 7. Influence of external pH on the uptake of 0.1 mmol l^–1 [¹⁴C]oxalate into hepatopancreatic BBMV. Vesicles contained 100 mmol l^–1 TMA-Cl, 50 mmol l^–1 K-gluconate, 50 µmol l^–1 valinomycin and 40 mmol l^–1 Hepes-Tris at pH 7.0. Incubation media contained 100 mmol l^–1 TMA-gluconate and 50 mmol l^–1 K-gluconate, and pH was adjusted to 7.0 (•) or 8.0 ( ${circ}$ ) with Hepes-Tris, or pH 5.0 ( ${blacksquare}$ ) or 6.0 ( ${square}$ ) with Mes-Tris.
