The activities of ouabain-sensitive (Na-K-) and ouabain-insensitive ATPases were determined in 3.6 mM calcium-containing and calcium-free media. Three lens tissue segments were studied: the epithelium/capsule segment, the anterior cortical segment and the posterior cortical segment. In the presence of calcium, the Na-K-ATPase activity in each segment was reduced, whereas the ouabain-insensitive ATPase activity in each segment was increased.
