“…Most workers (e.g. Himwich, Fazikas, Barker & Hurlburt, 1934;Gemmill, 1941;Gilmore & Samuels, 1949) Hastings (1949) both found that more glucose was assimilated by diaphragm muscle during incubation than could be accounted for by new glycogen or respiratory C02. Diaphragm is known to have a high rate of aerobic glycolysis, and it seemed likely that at least a part of the glucose had been transformed to lactic acid, and so had not been measured.…”
