10 LIGHT AND LIFE 



energy together with its P-O-P, in relatively simple classic chemical 

 reactions. Its other function is to produce a^'s. This it does, (accord- 

 ing to the theory which dominates my research) by converting the 

 bond-energy of its POP's into electronic energy again, the same 

 electronic energy which was invested in it, which was driving life 

 at its beginning, endless millions of years ago when it captured the 

 first photons. 



We can approach these fascinating problems by studying the various 

 reactions which may be involved, one by one. Our present meeting 

 will be devoted to the type of reaction which initiates photosynthesis 

 and probably led to the appearance of life on this globe.
