Fig. 3. Time course of 0.1 mmol l^–1 [¹⁴C]oxalate uptake by hepatopancreatic BBMV. Vesicles were preloaded with 100 mmol l^–1 TMA-gluconate, 25 mmol l^–1 K-gluconate, 25 mmol l^–1 KCl and 50 µmol l^–1 valinomycin ( ${blacksquare}$ ), 150 mmol l^–1 TMA-gluconate and 50 mmol l^–1 µmol l^–1 CCCP ( ${square}$ ) or 100 mmol l^–1 TMA-gluconate, 50 mmol l^–1 K-gluconate and 50 µmol l^–1 valinomycin (•). Incubation media contained 100 mmol l^–1 TMA-gluconate and 50 mmol l^–1 K-gluconate ( ${blacksquare}$ , •) or 100 mmol l^–1 K-gluconate and 50 mmol l^–1 TMA-gluconate ( ${square}$ ). All media contained 40 mmol l^–1 Hepes-Tris at pH 7.0.
