The Cl(-) energy gradient across the luminal membrane of Aplysia foregut epithelial cells is directed downhill from the lumen to the cellular cytosol. No primary or secondary active transporters had been shown to be involved in Cl(-) translocation across the luminal membrane. Cl(-) channel blockers impeded the movement of Cl(-) from the lumen into the foregut cellular cytosol. It was concluded that the primary means of Cl(-) transport across the luminal membrane was via Cl(-) conductance.
海兔前肠上皮细胞腔面膜两侧的Cl⁻能量梯度是从管腔向细胞溶质的下坡方向。尚未发现有初级或次级主动转运蛋白参与Cl⁻跨腔面膜的转运。Cl⁻通道阻滞剂阻碍了Cl⁻从管腔进入前肠细胞溶质。得出的结论是，Cl⁻跨腔面膜转运的主要方式是通过Cl⁻电导。
