The cytochrome system in mitochondria of unfertilized sea urchin eggs

1958

Abstract 1. 1. The cytochrome system of unfertilized sea urchin eggs has been studied using preparations of isolated mitochondria. 2. 2. The difference spectra of isolated mitochondria show the presence of a complete and operating cytochrome system formed by the cytochromes a , a 3 , b and c . 3. 3. This cytochrome system is very similar to that of mammals and yeast as demonstrated by spectrophotometric and manometric experiments.
