In the presence of methylene blue there is a very considerable increase in the production of [14C]carbon dioxide from [14C-1]glucose, and a corresponding decrease in the label in lactate and pyruvate, although the total radioactivity in (lactate + pyruvate + carbon dioxide) is the same as in the control incubation
