The photodissociation of the CO compound of cytochrome a/sub 3/ at liquid nitrogen temperatures was demonstrated. Since the recombination of CO does not occur in a measurable rate at 77 deg K, the system provides a quantum counter for intracellular luminescence. A considerably higher uv sensitivity was found in mitochondrial suspensions and intact cells that contain DPNH than was observed in purified cytochrome oxidase (free of DPNH). Results are consistent with the viewpoint that excitation fluorescence of DPNH (maximum 340 m mu ) provides a highly efficient fluorescence emission in the region of 410--500 m mu . (H.M.G.)
