Comments After a comprehensive investigation of the factors that regulate Golgi pH, Schapiro et al. (primary source) concluded that the flux of counterions through the Golgi membrane was at least as high as in flux of protons driven by the V-ATPase. Golgi membrane potential was therefore assumed to be small or nonexistent.
