that the latter can react enzymatically with another mole- 

 cule of pentose phosphate to reform an additional mole- 

 cule of hexose-phosphate and a triose phosphate. The net 

 result of this cyclical series of reactions is the conversion of 

 one molecule of hexose monophosphate to three molecules 

 of carbon dioxide and one of triose phosphate. 



It is worth pointing out that this type of sugar break-
