Method "ATP/O stoichiometries with different respiratory substrates were determined from the average of phosphorylation rates vs. respiratory rates in two different systems: (i) ATP production was monitored either by glucose 6-phosphate formation in the presence of non-limiting amount of hexokinase, 1 mM MgCl2 and 10 mM glucose, or (ii) by labelled Pi incorporation in adenine nucleotides as described in Ref. 7. These two methods gave identical results indicating that neither contaminating ATPase activity nor adenylate kinase activity changed significantly the ATP synthesis rate estimations."
