carbon dioxide occurs, no added compounds are present that could 

 be used as hydrogen donors, and the phosphoryl at i ng system, which 

 is assumed to function in a cyclic manner and thereby serve as a 

 short-circuit between the photochemi cal ly produced reductant(s) 

 and oxidant(s), is uncoupled by certain chemical agents.
