Abstract

Lactic acid production in the presence of high oxygen tensions (aerobic glycolysis) was found to occur in the teleost retina. Forty-two percent more glucose was utilized and 33% more lactic acid was produced under anaerobic than under aerobic conditions. Glycolysis was inhibited 33% by elevated oxygen (Pasteur effect), and it was further demonstrated that glycolysis is dependent upon the integrity of the retinal cells, being almost completely abolished by cellular disruption.
