Abstract
The yield of energy transfer from photosystem II to photosystem I in Porphyridium cruentum varies from a minimum value of about 0.50 when the photosystem II reaction centers are all open to a maximum value between 0.90 and 0.95 when the centers are all closed.
Keywords: energy distribution, chlorophyll, phycobilin, phycoerythrin, photosynthetic apparatus
