Energy and Electron Transfer Systems of Chlamydomonas reinhardi. I. Photosynthetic and Respiratory Cytochrome Systems of the Pale Green Mutant

The role of cytochromes in photosynthetic electron transfer system has been studied using the pale green mutant of Chlamydomonas reinhardi (ATCC 18302). The existence of cytochromes b₅₆₃ and f is confirmed, while no significant amount of ascorbate-reducible cytochrome b₅₅₉ is detected in this mutant. The presence of cytochrome c and a small amount of a-type cytochrome is determined in these cells.
