.... HPLC reverse-phase C-18, used for measurement of ATP content, established a value of 1.62 μmol ATP g –1 dry mass in sponge medulla, as opposed to 0.04 μmol ATP g –1 dry mass in the cortex, thus indicating a specific and defined energy distribution. These results correlate with the mitochondria...
