... in the activity of basolateral Na + /K + -ATPase (NKA) and apical V-type H + -ATPase (VA) and (2) region-specific Na + and K + flux rates. Both indicate a prominent role for the hindgut (rectum) in K + reabsorption. MTs also exhibit region-specific differences in Na + and K + flux rates that are coupled...

... reduced NH 3 /NH 4 + excretion rates, but they returned to control values following 24 h acclimation. These mussels had increased abundance of V-type H + -ATPase in the apical membranes of plicate organ cells; however, NH 3 /NH 4 + excretion rates were not affected by the V-type H + -ATPase specific...

... in the anal papillae suggests that, in addition to AeAmt1, the ionomotive pumps V-type H + -ATPase and Na + /K + -ATPase as well as NHE3 are involved in ammonia excretion at the anal papillae. The voltage gradients obtained from the ASET software program were converted into concentration gradients using...

... for a successful terrestrial invasion. Crabs can actively uptake or excrete ions upon salinity change, and the gills play a major role among the osmoregulatory organs. Several enzymes are involved in the osmoregulatory process, including Na + ,K + -ATPase and V-type H + -ATPase (V-H + -ATPase). Na + ,K + -ATPase...
