ability barriers of the cell.^ Studies with such preparations possibly 

 will provide evidence that the cellular organization of photosynthetic 

 bacteria resembles that of other types of cells in the sense that "... 

 electron transport- coupled generation of ATP and ATP-dependent 

 energy andiontransportmay be specialized manifestations of a common 

 enzymic function, inherent in cellular membrane structures, . ," (15),
