The discovery of James and Beevers (1950) that the rapid oxidation processes characteristic of spadix tissue were not significantly infiuenced by cyanide suggested that a cytochrome system was not involved. The subsequent work of Hackett and Simon (1954) showed that part of the respiratory activity could be recovered from a particulate fraction obtained from the tissue homogenate; also they found that the particles were able to oxidize succinate as well as other carboxylic acids. Recently James and Elliott (1955) have obtained further evidence leading to the conclusion that the particles from the spadix resemble the mitochondria obtained from many plant and animal tissues in their ability to oxidize components of the tricarboxylic acid cycle but differ in respect to the lack of inhibition shown by the Arum particles in presence of cyanide. Since the succinoxidase system in the particulate fraction from many types of cell has so far always been found to be associated with the presence of cytochrome components it was important to see whether the spadix tissue was exceptional in this respect.
