Question

The toxicity of blue light to P. acnes is due to the high levels of endogenous porphyrins in this bacterium. Porphyrins are large heterocyclic organic molecules required for synthesis of cellular components such as the heme groups of cytochromes. If you wanted to study P. acnes cytochromes, which cellular fraction would you isolate? Choose one: A. plasma membrane B. periplasm C. cytoplasm D. capsule
