1. Using intact cells of Chlorella, the effects cf CO_2 on the levels of oxidized and reduced forms of DPN and TPN in the light and in the dark were investigated. 2. It was found that the light-induced changes of the DPNH-level were not affected by the presence or absence of CO_2 On the other hand, the light-induced increase of TPNH was suppressed in the presence of CO_2 and the level of TPNH which was raised on illumination in the absence of CO_2 was lowered by the provision of CO_2. 3. On the basis of these findings, it was concluded that TPNH, but not DPNH, is participating, in some way, in the mechanism of photosynthesis. 4. Discussions were made on the difference in the sites of participation of TPNH and of the photogenic reducing agent (R) in the path of carbon in photosynthesis.
