We study the intrinsic (i.e., homocellular) mechanisms responsible for regulation of enterocyte volume during periods of nutrient absorption in the intestine of Aplysia californica. During transcellular alanine absorption, the K ⁺ conductance of the enterocyte's apical membrane increases. Our investigation focuses on the mechanism that increases the number of active K ⁺ channels. Our results suggest that K ⁺ channels are delivered to apical membranes by exocytic insertion of these channels from intracellular vesicles.
