Abstract
The increase in respiration on the addition of ascorbic acid to liver slices of guinea-pigs on a normal diet was markedly less than of those animals on a restricted diet or on a scorbutic diet; the rise in Qoa in these 2 groups was of the same order. The total resp. of the liver tissue from the animals on the restricted diet was, after the addition of ascorbic acid, on the whole, higher than that of the liver tissue from the animals on a normal diet.
