THE EFFECT OF CARBON DIOXIDE TENSION ON TISSUE METABOLISM (RETINA)

Abstract
The metabolism of rat retina was found to be sensitive to the concentration of the carbon dioxide-bicarbonate buffer system. Increasing the carbon dioxide from 1 per cent to 5 per cent at constant pH nearly doubled both respiration and glycolysis. Increasing the carbon dioxide at constant pH from 5 per cent to 20 per cent had no effect on glycolysis, but depressed the QOO2 from 31 to 19.
