Na+ + K+ A TPase activity For animals acclimated to 32 ppt salinity, whole-gill homogenates had ouabain-sensitive Na+ + K+ ATPase activities in the range of 35-65 nmol Pi mg pro~' min~'; activity in the coxal gland was significantly higher at about 120 nmol Pi mg pro"1 min ' (Fig. 6). Moreover, while activity among whole-gill homogenates was vari- able, the distinctive anterior-posterior differences in Na+ + K+ ATPase activity seen in crustacean gills were clearly absent. Gill numbers 2 and 3 had significantly.
