| The Effect of Deoxycholate-Treatment to the Photoreactions of the Active Pigments in Photosynthesis  | | | | Abstract
| In the heavy fraction of deoxycholate-treated spinach chloroplasts the chlorophyll an activity is high and the chlorophyll a\ activity is low when no artificial electron donor is added. The addition of the photosystem I donor system N-methyl-phenazonium sulphate plus sodium ascorbate (PMS + Asc) leads to a complete reactivation of the chlorophyll ai reaction. The addition of the photo system II donor system p-benzohydroquinone plus sodium ascorbate (HQ + Asc) leads to an inhibi tion of the chlorophyll an activity. From these results we conclude: 1. Besides an interruption of the linear electron flow between the two photosystems deoxycholate-treatment leads to a block of the electron flow from water to photosystem II. 2. In deoxycholate-treated chloroplasts the linear electron flow in photosystem II just like in Tris washed, heat-treated or aged chloroplasts, is replaced by a cyclic one. | | | |
