Transport energetics of the Cl~- pump in Aplysia gut

摘要

Basolateral membranes of Aplysia foregut epithelia contain an ATP-dependent Cl- transporter (Cl- pump). Increased activity of the Cl- pump, coupled to apical and basolateral membrane depolarization, changed the Cl- transport energetics across the apical membrane but did not change the vectorially-opposite Cl- transport energetics across the basolateral membrane.
