  1. ATPase activity of isolated D10 plasma membranes tested without nucleotide and absorbance due to the nucleotide hydrolysis was subtracted. Values are means of three separate experiments, each performed in quadruplicate ± standard deviations and are expressed as % of control in presence of ATP. N.D.: not determined.
