Summary Activities of cytochrome oxidase and succinic dehydrogenase in the heart, liver and brain of the developing human fetus were determined. During the development of the human fetus, there was a rise of cytochrome oxidase and succinic dehydrogenase in all of organs analysed. In the heart, the increase in both enzyme activities, particularly succinic dehydrogenase, was found throughout the fetal life, whereas in the liver and brain it was found to occur only during the relatively early fetal periods. The increase in the enzyme activity exceeds that of tissue protein.
