RESULTS AND DISCUSSION The respiratory quotient of the Ascophyllum segments was Since the en- zyme systems involved in Ascophyllum respiration are not known, it was thought feasible to make a survey of the effect of substances that are known to serve as re- spiratory substrates and inhibitors in other types of cells. Of the sugars tested, su- crose and glucose stimulated oxygen uptake of the segments up to 20 per cent, as indicated in Table III. Mannitol, a storage product of Ascophyllum, had no effect.
