in kidneys from fed rats , when glucose was absent , lactate production was only 12 mumol/h per g dry wt , and in kidneys from starved rats there was no lactate production , indicating that neither the phosphoenolpyruvate/pyruvate substrate cycle nor other analogous cycles for the recycling of lactate carbon are operating in the intact kidney cortex .
