Abstract

OXIDATION of a c-type cytochrome by light absorbed by the photosynthetic system of the purple sulphur bacterium, Chromatium, at the temperature of liquid nitrogen was discovered by Chance and Nishimura1. Vredenberg and Duysens2 made further measurements confirming that quantum efficiencies did not change by more than a factor of two, if that much, at the lowest temperatures. The light and instrument limitations on these measurements make any further conclusions about rates difficult.
