Abstract
A comparison was made of radiochemical yields of CO2 from glucose-6-c14 and glucose -1-C14 on incubation with various rabbit tissues. Brain slices catabolized glucose practically entirely via the Embden-Meyerhof (E.M.) pathway. The other tissues studied, particularly testis and bone marrow, formed CO2 in greater yield from C-1 of glucose than from C-6 of glucose.
