Spectroscopic measurements on cultures of Prototheca zopfii irradiated with blue light revealed that inhibition of respiration was accompanied by destruction of cytochrome a3. One of the three b-type cytochromes and one of the two c-type cytochromes of this organism were also affected. Cytochrome oxidase of yeast (not resolved into the a and a3 components) and cytochrome a3 of beef-heart mitochondria were also destroyed by blue light.
