Abstract: | Suspensions of light particles sedimented at 16500×g from pea subchloroplast preparations were investigated. The exciting light readily caused the photooxidation of P700 in a fraction of active particles. The effective energy transfer has been shown to occur between individual P700. The quantum yield of P700 photooxidation was estimated by means of the relative method to be ?0.75. |
