The nonoxidative glycolysis (NOG) pathway can achieve stoichiometric carbon recovery for sugar-derived biosynthesis. NOG can depend on either FBPase or SBPase catalyzed step to provide the driving force for the carbon rearrangement reactions. Please draw out three circular versions of the NOG pathway that are SBP-dependent (i.e. the driving force for the NOG will be provided by the phosphoketolase (PK) and SBPase catalyzed steps) and PK either catalyzing F6P only, X5P only, or 1 F6P/2 X5P.
