Yeast, 10 per cent; glucose, 6 per cent; under oxygen and nitrogen alternatively; temp. 30°. of triose phosphate dehydrogenase caused by respiration. In an attempt to overcome the difficulty, we considered the possibility of some of the inorganic phosphate in the cell, as determined by the molybdenum blue method, being present not as free phosphate, but as having existed as some labile phosphorus compound, acyl phosphate, which had become hydrolysed during assay (Lynen, 1941; Kamen and Spiegelman, 1948). More recent observations and the negative result of attempts to find noticeable amounts of acyl phosphate in respiring or fermenting yeast cells (Holzer, 1949) made it.
